Loss Contingency [Abstract]
Contingencies	ContingenciesSince early March 2020, efforts to slow the spread of the COVID-19 virus have had a significant impact on the U.S. economy. We continue to follow the policies described in Notes 1 and 2 to our Consolidated Financial Statements contained in our 2019 Annual Report on Form 10-K, including those related to impairments of real estate assets and investments in unconsolidated affiliates, leases and estimates of credit losses on operating lease receivables. While the results of our current analyses did not result in any material adjustments to amounts as of September 30, 2020 and during the three and nine months ended September 30, 2020, circumstances related to the COVID-19 pandemic may result in recording impairments, lease modifications and credit losses in future periods.

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.
