[1] Purchase price includes capitalized transaction costs of $2.1 million.

[2] On January 23, 2025, the Company acquired an additional 48% economic ownership interest, and increased its existing 20% interest to 68%, in the Renaissance Portfolio primarily located in Washington D.C. The 48% interest was acquired for a purchase price of $117.9 million, based upon a gross portfolio fair value of $245.7 million, which included existing mortgage loan indebtedness of $156.1 million in aggregate (Note 7). Prior to the acquisition, the Company accounted for its 20% interest under the equity method of accounting (Note 4). Due to the Company gaining a controlling financial interest as a result of this acquisition, the Company determined it should consolidate its investment within its Core Portfolio effective January 23, 2025. As such, the Company measured and recognized 100% of the identifiable assets acquired, the liabilities assumed and any noncontrolling interests of the Renaissance Portfolio, at fair value and recognized a $9.6 million loss on change in control representing the difference between the carrying value and fair value of its existing equity method interest immediately before consolidation of the portfolio in its Condensed Consolidated Statements of Operations related to the remeasurement of its previously held equity interest.
