As a result, the Company considers Windfield to be a variable interest entity (“VIE”). However, the Company does not consolidate Windfield as it is not the primary beneficiary. The carrying amount of our 49% equity interest in Windfield, which is our most significant VIE, was $291.6 million and $280.2 million at June 30, 2016 and December 31, 2015, respectively.

Our unconsolidated VIE’s are reported in Investments in the condensed consolidated balance sheets. The Company does not guarantee debt for, or have other financial support obligations to, these entities, and its maximum exposure to loss in connection with its continuing involvement with these entities is limited to the carrying value of the investments.
