(1) Sales price represents the gross sales price for a property or the gross asset valuation for interests in a property.

(2) The gain on sale for 102 Greene Street is net of $0.9 million in employee compensation awards accrued in connection with the realization of the investment gain as a bonus to certain employees that were instrumental in realizing the gain on sale. Additionally, gain on sale amounts do not include adjustments for expenses recorded in subsequent periods.

(3) In February 2016, we closed on the sale of 885 Third Avenue. The sale did not meet the criteria for sale accounting and as a result the property remained on our consolidated financial statements until the criteria was met in April 2017.

(4) In April 2017, we closed on the sale of a 90% interest 102 Greene Street and had subsequently accounted for our interest in the property as an investment in unconsolidated joint ventures. We sold the remaining 10% interest in September 2017. See Note 6, "Investments in Unconsolidated Joint Ventures".
