The financial statements have been reclassified for all periods presented.

Lithium Second Quarter Net sales decreased primarily from lower volumes of organometallic products, driven mostly by butyllithium, and a 26% reduction in potash sales, mainly volumes. This was largely offset by significantly higher volumes of battery applications. Adjusted EBITDA decreased primarily from net sales, partially offset by the results of a 49% ownership interest in Talison Lithium in May 2014. Net sales do not include sales made by Talison Lithium. See Appendices for reconciliation of non-GAAP measures and potash sales.

Surface Treatment Second Quarter Net sales increased primarily due to increased volumes in most markets, particularly driven by higher automotive OEM and automotive components, coil and cold forming, general industry and aerospace applications; the impact of the acquisition of the remaining 50% interest in a previously unconsolidated joint venture in India; and higher selling prices. Adjusted EBITDA increased primarily from higher net sales, partially offset by higher selling, general and administrative costs.
