[1] The gains we recognize in Gains on Dispositions of Development Properties and Land, Net are principally driven by the contribution of newly developed properties to our unconsolidated co-investment ventures and occasionally sales to a third party.

[2] During the three and six months ended June 30, 2023, we sold our ownership interest in an unconsolidated office joint venture.
