[1] These ventures are considered VIE’s under the new consolidation guidance discussed in Note 1. Based on our evaluation, the noncontrolling interests in these ventures do not hold substantive participating or kick-out rights and therefore as a group they lack the power to direct the significant activities of these ventures that most significantly impact the venture’s economic performance. We have both the power to direct the significant activities and the obligation to absorb losses and the rights to receive benefits from these ventures. As a result, we are the primary beneficiary of both ventures and consistent with prior reporting periods, we consolidate each venture within our financial statements.

[2] The assets of Prologis Brazil Logistics Partners Fund I (“Brazil Fund”) are primarily investments in unconsolidated entities of $119.5 million and $103.1 million at June 30, 2016, and December 31, 2015, respectively. For additional information on our unconsolidated investments, see Note 4.

[3] This line item includes our two partnerships that have issued limited partnership units to third parties, as discussed above, along with various other consolidated entities. At June 30, 2016, and December 31, 2015, limited partnership units were exchangeable into cash or, at our option, 1.8 million shares of the Parent’s common stock.

[4] At June 30, 2016, and December 31, 2015, excluding the Class A Units, there were common limited partnership units in the Operating Partnership that were exchangeable into cash or, at our option, 5.5 million shares and 6.4 million shares of the Parent’s common stock with a fair value of $271.9 million and $275.0 million, respectively, based on the closing stock price of the Parent’s common stock. In 2016, unitholders exchanged 0.9 million common limited partnership units into an equal number of shares of the Parent’s common stock with a value of $25.4 million. At June 30, 2016, and December 31, 2015, there were 2.1 million and 1.2 million LTIP Units (as defined in Note 9) outstanding, respectively, associated with our long-term compensation plan that are exchangeable into common units of the Operating Partnership and redeemable into the Parent’s common stock after they vest and other applicable conditions are met.

[5] At June 30, 2016, and December 31, 2015, we had 8.9 million Class A Units that were convertible into 8.8 million common limited partnership units of the Operating Partnership.
