[1] This venture represents four separate joint ventures, with four separate accounts managed by Prudential Real Estate Investors ("PREI"), three of these ventures are collectively referred to as KimPru and the remaining venture is referred to as KimPru II. During the year ended December 31, 2014, KimPru recognized impairment charges of $21.4 million related to the decline in value of two operating properties. The Company had previously taken other-than-temporary impairment charges on its investment in KimPru and had allocated these impairment charges to the underlying assets of the KimPru joint ventures including a portion to these operating properties.

Upon completion of these transactions, Blackstone and the Company entered into a new joint venture (Kimstone) in which the Company owns a 33.3% noncontrolling interest.

During the year ended December 31, 2013, BIG recognized a gain on early extinguishment of debt of $13.7 million related to a property that was foreclosed on by a third party lender. The Company's share of this gain was $2.4 million.

[19] During June 2013, the Intown portfolio was sold for a sales price of $735.0 million which included the assignment of $609.2 million in debt. This transaction resulted in a deferred gain to the Company of $21.7 million. The Company maintains its guarantee on a portion of the debt ($139.7 million as of December 31, 2014 and 2013) assumed by the buyer. Due to this continued involvement, the Company deferred its gain until such time that the guarantee and commitment expire.
