[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, 2019 and 2018, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018 ($611.5 million and $635.9 million, respectively); (ii) recording additional costs associated with our investment in the venture ($87.2 million and $94.4 million, respectively); (iii) receivables, principally for fees and promotes ($152.0 million and $166.7 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to NPR, as discussed above. For deferred gains from partial sales recorded prior to January 1, 2018, we recognize these gains over the lives of the underlying real estate properties or at the time of disposition to a third party.

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

[3] As discussed above, the formation of PCCLF in 2019 increased the number of ventures in Asia.

[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.
