[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 March 31, 2019 and December 31, 2018, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018 ($627.4 million and $635.9 million, respectively); (ii) recording additional costs associated with our investment in the venture ($88.4 million and $94.4 million, respectively); (iii) receivables, principally for fees and promotes ($100.9 million and $166.7 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to Nippon Prologis REIT, Inc. ($122.0 million for both periods).

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

[3] In February 2019, we redeemed a portion of our investment in Prologis European Logistics Fund (“PELF”) for €278.2 million ($313.3 million). At March 31, 2019 our ownership in PELF was 24.3%.

[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.
