SUBSEQUENT EVENTS | 21. SUBSEQUENT EVENTS On February 2, 2021, the Company formed a joint venture with an unaffiliated third party to develop a 570,000 square foot mixed-use building at property under a long-term ground lease of 3025 JFK Boulevard, Philadelphia, Pennsylvania, also known as "Schuylkill Yards West." The estimated project cost is approximately $287 million, and the joint venture partner has agreed, subject to customary funding conditions, to fund up to approximately $58 million of the project costs in exchange for a 45% preferred equity interest in the venture. We have agreed to provide a completion guaranty in connection with the development of the project.
