Organization, Consolidation and Presentation of Financial Statements [Abstract]

Our interim condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not necessarily include all information and footnotes necessary for a fair statement of our condensed consolidated financial position, results of operations, and cash flows in accordance with generally accepted accounting principles in the United States (“GAAP”).

Basis of Consolidation

Our condensed consolidated financial statements reflect all of our accounts, including those of our controlled subsidiaries. The portions of equity in consolidated subsidiaries that are not attributable, directly or indirectly, to us are presented as noncontrolling interests. All significant intercompany accounts and transactions have been eliminated.

Variable Interest Entity

When we obtain an economic interest in an entity, we evaluate the entity to determine if it should be deemed a VIE and, if so, whether we are the primary beneficiary and are therefore required to consolidate the entity.

Reclassification

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

Beginning with the first quarter of 2020, we present Reimbursable tenant costs on its own line item in the condensed consolidated statements of operations. Previously, this line item was included within Property expenses (which is now presented as Property expenses, excluding reimbursable tenant costs).
