[1] Prologis’ investment balance is presented at our adjusted basis derived from the ventures’ U.S. GAAP information. The difference between our ownership interest of a venture’s equity and our investment balance at December 31, 2020 and 2019, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018 ($589.3 million and $611.5 million, respectively); (ii) recording additional costs associated with our investment in the venture ($101.5 million and $87.2 million, respectively); (iii) receivables, principally for fees and promotes ($165.6 million and $152.0 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to NPR, as discussed above.

[2] In 2020, USLF acquired a portfolio of 108 operating properties, aggregating 18.3 million square feet, in the IPT Transaction for cash consideration of $2.0 billion, including transaction costs and the assumption and repayment of debt.

[3] PBLV and our other Brazilian joint ventures are combined as one venture for the purpose of this table.

[4] Represents our weighted average ownership interest in all unconsolidated co-investment ventures based on each entity’s contribution of total assets before depreciation, net of other liabilities.
