_______________ (1)See Note 4. (2)Includes pre-development costs. Acquisition On December 14, 2023, the Company completed the acquisition of its joint venture partner’s 45% interest in the joint venture entity that owns Santa Monica Business Park located in Santa Monica, California (See Note 6). Santa Monica Business Park is a 47-acre office park consisting of 21 buildings totaling approximately 1.2 million net rentable square feet. Approximately 70% of the rentable square footage is subject to a ground lease with 75 years remaining, including renewal periods (See Note 4). The property is subject to existing mortgage indebtedness of $300.0 million (See Note 7). The acquisition was completed for a gross purchase price of $38.0 million and the Company acquired net working capital, including cash and cash equivalents of approximately $20 million. The purchase of the joint venture partner’s interest was at a discount and therefore the net assets were recorded at the Company’s relative fair value. Prior to consolidation, the Company had an approximately $149.9 million investment in the joint venture. As the purchase was at a discount, the gain on consolidation was calculated based on the Company’s share of the determined fair market value of the net acquired assets. This resulted in the Company recording a gain upon consolidation of approximately $29.9 million, which is included within income (loss) from unconsolidated joint ventures in the Consolidated Statement of Operations. The total equity acquired was equal to the Company’s share of the calculated fair market value, used in the gain on consolidation calculation, plus the cash consideration paid. The difference between the determined fair market value and recorded equity is adjusted based on the relative fair value and used to calculate the net assets that were recorded. The following table summarizes the allocation of the relative fair value of the net assets the Company received at the date of acquisition for Santa Monica Business Park (in thousands):

Building and improvements | 390,305 |
