[1] | During 2021, the Company purchased its partner’s 70.0% remaining interest in Jamestown Portfolio, which is comprised of six property interests. The Company then entered into a joint venture with Blackstone Real Estate Income Trust, Inc. (“BREIT”) in which it contributed these six properties for a gross sales price of $425.8 million, including $170.0 million of non-recourse mortgage debt. As a result, the Company no longer consolidates these six property interests and recognized a loss on change in control of interests of $0.4 million. The Company has a 50.0% investment in this joint venture ($130.1 million as of the date of deconsolidation), included in Investments in and advances to real estate joint ventures on the Company’s Consolidated Balance Sheets.
[2] | Includes the sale of a land parcel at a development project located in Dania Beach, FL for a sales price of $32.5 million, which resulted in a gain of $4.3 million.
