[1] On January 8, 2020, our two U.S. co-investment ventures, Prologis Targeted U.S. Logistics Fund, L.P. (“USLF”) and Prologis U.S. Logistics Venture, LLC (“USLV”), acquired the wholly-owned real estate assets of Industrial Property Trust Inc. (“IPT”) for $2.0 billion each in a cash transaction, including transaction costs and the assumption and repayment of debt (the “IPT Transaction”). As we consolidate USLV, the number of operating properties, square feet and acquisition cost for the properties acquired by USLV are included in the consolidated acquisition activity.
