Investments	Investments: The Company holds a 49% equity interest in Talison Lithium Pty. Ltd. (“Talison”), which we acquired in the Rockwood acquisition. With regards to the Company’s ownership in Talison, the parties share risks and benefits disproportionate to their voting interests. As a result, the Company considers Talison to be a variable interest entity (“VIE”). However, the Company does not consolidate Talison as it is not the primary beneficiary. The carrying amount of our 49% equity interest in Talison, which is our most significant VIE, was $444.8 million at March 31, 2015. The Company’s aggregate net investment in all other entities which it considers to be VIE’s for which the Company is not the primary beneficiary was $32.9 million and $6.2 million at March 31, 2015 and December 31, 2014, 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.
