Basis of Presentation The accompanying unaudited consolidated financial statements include the accounts of all controlled subsidiaries, and all significant intercompany amounts have been eliminated. Due to the seasonal nature of certain operational activities, the results for the interim period ended March 31, 2017 are not necessarily indicative of the results to be expected for the full year. These consolidated financial statements have been prepared in accordance with the instructions to Form 10‑Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (GAAP) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments necessary for fair presentation (including normal recurring accruals) have been included. The consolidated financial statements in this Form 10‑Q should be read in conjunction with the audited consolidated financial statements and related notes contained in the combined 2016 Annual Report on Form 10‑K of Simon and the Operating Partnership. As of March 31, 2017, we consolidated 134 wholly‑owned properties and 17 additional properties that are less than wholly‑owned, but which we control or for which we are the primary beneficiary. We account for the remaining 78 properties, or the joint venture properties, as well as our investments in Klépierre, Aéropostale, and HBS Global Properties, or HBS, using the equity method of accounting, as we have determined we have significant influence over their operations. We manage the day‑to‑day operations of 57 of the 78 joint venture properties, but have determined that our partner or partners have substantive participating rights with respect to the assets and operations of these joint venture properties. Our investments in joint ventures in Japan, South Korea, Mexico, Malaysia, Germany, Canada, and the United Kingdom comprise 17 of the remaining 21 properties. These international properties are managed by joint ventures in which we share control. Preferred distributions of the Operating Partnership are accrued at declaration and represent distributions on outstanding preferred units of partnership interests, or preferred units, and are included in net income attributable to noncontrolling interests. We allocate net operating results of the Operating Partnership after preferred distributions to limited partners and to Simon based on the partners’ respective weighted average ownership interests in the Operating Partnership. Net operating results of the Operating Partnership attributable to limited partners are reflected in net income attributable to noncontrolling interests. Simon’s weighted average ownership interest in the Operating Partnership was 86.9% and 85.6% for the three months ended March 31, 2017 and 2016, respectively. As of March 31, 2017 and December 31, 2016, Simon’s ownership interest in the Operating Partnership was 86.8% and 86.9%, respectively. We adjust the noncontrolling limited partners’ interests at the end of each period to reflect their interest in the net assets of the Operating Partnership. Preferred unit requirements in the Operating Partnership’s accompanying consolidated statements of operations and comprehensive income represent distributions on outstanding preferred units and are recorded when declared.
