[1] At December 31, 2014 and 2013, there were limited partnership units in the Operating Partnership that were exchangeable into cash or, at our option, 1,767 shares of the Parent's common stock. In 2014, no limited partnership units were redeemed for cash or the Parent's common stock. As discussed in Note 13, we issued an additional 113 LTIP Units in connection with the PPP (both as defined below) in the third quarter of 2014 that are not exchangeable until they vest. All of these outstanding limited partnership units receive quarterly cash distributions equal to the quarterly distributions paid on our common stock pursuant to the terms of the partnership agreement.
[2] In 2014, AFORES contributed its remaining operating properties and the balance of its secured debt to FIBRA Prologis in two separate transactions. The difference between the amount received and the noncontrolling interest balance related to the properties contributed was $34.6 million, and was adjusted through equity with no gain or loss recognized. See Notes 4 and 5 for more information on these transactions.
