Impairment Charges [Abstract]
Asset Impairment Charges [Text Block]	Impairment ChargesThe Company reviews its properties for changes in circumstances that indicate that the carrying value of a property may not be recoverable based on an estimate of undiscounted future cash flows. As a result of the COVID-19 pandemic, many of the Company's properties have just recently re-opened or are temporarily closed and the Company has negotiated and continues to negotiate lease modifications with customers that include rent deferrals, rent reductions or other modifications. As part of this process, the Company reassessed the expected holding periods of such properties, and determined that the estimated cash flows were not sufficient to recover the carrying values of eight properties. Two of these eight properties have operating ground lease arrangements with right-of-use assets. During the nine months ended September 30, 2020, the Company determined the estimated fair value of the real estate investments and right-of-use assets of these properties using independent appraisals and various purchase offers. The Company reduced the carrying value of the real estate investments, net to $45.6 million and the operating lease right-of-use assets to $13.0 million. The Company recognized impairment charges of $47.8 million on the real estate investments and $15.0 million on the right-of-use assets, which are the amounts that the carrying value of the assets exceeded the estimated fair value. During the nine months ended September 30, 2020, the Company also recognized $3.2 million in other-than-temporary impairments related to its equity investments in joint ventures in three theatre projects located in China. See Note 9 for further details on these impairments.
