Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements include our accounts and those of our consolidated subsidiaries. All intercompany amounts have been eliminated. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Our most significant estimates include current expected credit losses. Actual results could differ from those estimates. These unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021 ("Annual Report"), as filed with the Securities and Exchange Commission (the "SEC"). In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary to present fairly our financial position, results of operations and cash flows have been included. Our results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the full year or any other future period. We currently operate in one reporting segment. Risks and Uncertainties During the first quarter of 2020, there was a global outbreak of a novel coronavirus ("COVID-19"), which was declared by the World Health Organization as a pandemic. The ongoing COVID-19 pandemic has adversely impacted global economic activity and has contributed to significant volatility in financial markets. Due to various uncertainties, including the rise of new variants, the severity of such new variants, disparities in vaccination rates and vaccine hesitancy, the ultimate duration of the pandemic, and additional actions that may be taken by governmental authorities, further business risks could arise. Although more normalized activities have resumed and there has been improved global economic activity due to global and domestic vaccination efforts, we are not in a position to estimate the ultimate impact COVID-19 and its variants will have on our business and the economy as a whole, including longer-term macroeconomic effects on supply chains, inflation and labor shortages. For example, in response to recent inflationary pressure, the U.S. Federal Reserve and other global central banks have raised interest rates in 2022 and have indicated likely further interest rate increases. We believe the estimates used in preparing our financial statements and related footnotes are reasonable and supportable based on the best information available to us as of September 30, 2022. The uncertainty over the ultimate impact of COVID-19 and its variants, supply chain disruptions and labor shortages, rising inflation and increases in interest rates on the global economy generally and our business in particular may materially impact the accuracy of the estimates and assumptions used in the financial statements and related footnotes and, as a result, actual results may vary significantly from estimates. Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04 "Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"). ASU 2020-04 provides optional expedients and exceptions for applying GAAP to debt instruments, derivatives, and other contracts that reference London Interbank Offered Rate ("LIBOR") or other reference rates expected to be discontinued as a result of reference rate reform. This guidance is optional and may be elected through December 31, 2022 using a prospective application on all eligible contract modifications. We have loan agreements, debt agreements, and an interest rate cap that incorporate LIBOR as a referenced interest rate. It is difficult to predict what effect, if any, the phase-out of LIBOR and the use of alternative benchmarks may have on our business or on the overall financial markets. During the fourth quarter of 2021, we adopted optional expedients per ASU 2020-04 for certain of our commercial mortgage loans and debt agreements denominated in British Pound Sterling ("GBP") and Euro ("EUR") with contracts that reference GBP LIBOR and EUR LIBOR, respectively. As prescribed by the optional expedients within ASU 2020-04, we have accounted for applicable modified contracts that incorporate alternative benchmarks as if they are not substantially different. We will continue to evaluate the possible adoption of any such expedients or exceptions for certain of our commercial mortgage loans and debt agreements denominated in U.S. Dollars. In March 2022, the FASB issued ASU 2022-02 "Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures" ("ASU 2022-02"). The intention of ASU 2022-02 is to simplify the guidance surrounding loan modifications and restructurings and to eliminate the accounting guidance related to troubled debt restructurings ("TDR"). The new guidance deviates from TDR guidance as disclosures are now based on whether a modification or restructuring with a borrower experiencing financial difficulty results in principal forgiveness, an interest rate reduction, other-than-insignificant payment delay or term extension as opposed to simply a concession. The new guidance requires disclosure by class of financing receivables, of the types of modifications, the financial effects of those modifications and the performance of those modified receivables in the trailing twelve months after modification. Accounting for credit losses under ASC 326 "Financial Instruments—Credit Losses", is also updated to allow entities to use any acceptable method to determine credit losses as a result of modification or restructuring with a borrower experiencing financial difficulty. ASU 2022-02 also requires disclosure of gross write-offs recorded in the current period, on a year-to-date basis, by year of origination in the vintage disclosures. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022. Entities are able to early adopt these amendments, including adoption in an interim period, and have the ability to early adopt the TDR enhancements separately from the vintage disclosures. If an entity adopts the amendments in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes the interim period. During the third quarter of 2022, we have early adopted the TDR enhancements and new vintage disclosure requirements under of ASU 2022-02.
