Lithium Third Quarter Net sales decreased primarily from organometallic products, driven mostly by butyllithium from reduced sales volumes attributable to weaker pricing fundamentals in the Asian market. This was largely offset by higher volumes of battery applications. Adjusted EBITDA increased primarily from the contribution of $11.2 million from our 49% ownership interest in the Talison Lithium joint venture that was completed in May 2014, partially offset by lower net sales. Net sales do not include Talison Lithium’s sales. See Appendices for reconciliation of non-GAAP measures and potash sales.

Surface Treatment Third Quarter Net sales increased primarily due to increased volumes in most markets, particularly driven by higher automotive OEM and automotive components, aerospace, general industry and coil and cold forming applications; and, to a lesser extent, higher selling prices. Adjusted EBITDA increased primarily from higher net sales, partially offset by higher selling, general and administrative costs. Note: In the second quarter of 2014, Rockwood reorganized its Metal Sulfides business and began reporting it within the Surface Treatment segment.
