2022 Acquisitions

The following table summarizes the properties acquired during the year ended December 31, 2022:

Property	Acquisition Date	Property Type	Approximate Square Feet	Gross Asset Valuation (in millions)
245 Park Avenue (1)	September 2022	Fee Interest	1,782,793	$	1,960.0

(1)On October 31, 2021, HNA, through an affiliated entity, filed for Chapter 11 bankruptcy protection on account of its investment in 245 Park Avenue, together with another asset in Chicago. On July 8, 2022, certain of the debtors and affiliates of SL Green entered into a Plan Sponsorship and Investment Agreement (the "Plan"), pursuant to which SL Green became the stalking horse bidder for the property. Since the debtors did not receive any qualifying bids for the property and the Plan was confirmed, SL Green acquired full ownership and control of the property in September 2022, at which time our outstanding preferred equity and accrued interest balance were credited to our equity investment in the property. We recorded the assets acquired and liabilities assumed at fair value. See Note 5, "Debt and Preferred Equity Investments" and Note 16, "Fair Value Measurements."

As a result, it was determined that this investment is a VIE in which we are the primary beneficiary, and the investment was consolidated in our financial statements. Upon consolidating the entity, the assets and liabilities of the entity were recorded at fair value. Prior to January 2021, the investment was accounted for under the equity method. See Note 6, "Investments in Unconsolidated Joint Ventures" and Note 16, "Fair Value Measurements.

(2)In April 2021, the Company exercised its option to acquire the fee interest in the property from the ground lessor and the Company acquired the fee interest in June 2021. The Company held the leasehold interest in the property prior to exercising its option.

(3)In September 2021, the Company was the successful bidder for the fee interest in 690 Madison Avenue at the foreclosure of the asset. The property previously served as collateral for a debt and preferred equity investment. We recorded the assets acquired and liabilities assumed at fair value.
