(1) | Represents an unconsolidated interest in an entity that owns the land underlying one of the consolidated joint venture properties noted above and owns and operates a related parking facility. The consolidated joint venture entity, as a limited partner, does not have substantive kick-out or participating rights in the entity. As a result, the entity qualifies as a VIE, but the consolidated joint venture entity does not have a controlling financial interest in the VIE and is not the VIE’s primary beneficiary. As a result, the entity that owns the land and owns and operates the parking facility is unconsolidated and recorded using the equity method of accounting.
(2) | Represents unconsolidated interests in projects under development and land held for development. See further discussion below.
(3) | Represents unconsolidated investments in real estate technology funds/companies.
(4) | In certain instances, the joint venture agreements contain provisions for promoted interests in favor of our joint venture partner. If the terms of the promoted interest are attained, then our share of the proceeds from a sale or other capital event of the unconsolidated entity may be less than the indicated ownership percentage.
