Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rates for the three and nine months ended September 30, 2021 vary from the statutory U.S. federal income tax rate primarily due to the Company being designated as a REIT that is generally treated as a non-tax paying entity. During the three and nine months ended September 30, 2021, the effective tax rates were impacted by: (1) earnings generated by our foreign operations that are primarily permanently reinvested, (2) a change to the statutory tax rate in the United Kingdom and (3) the release of valuation allowance as a result of increased deferred tax liabilities that provide a positive source of income for valuation allowance assessment purposes. The increase in deferred tax liabilities were recorded due to certain acquisitions’ measurement period adjustments. As a result, the overall income tax benefit increased by $1.0 million and decreased by $5.5 million for the three months and nine months ended September 30, 2021, respectively, compared to the same periods in the prior year.
