ATOI in the fourth quarter was $70 million, up from $67 million in third quarter 2013, and up from $41 million in fourth quarter 2012. The sequential increase was driven by strong productivity savings and energy efficiency improvements, benchmark production levels, and sales at Alumina Price Index-based pricing, despite higher energy costs and lower LME-based prices. Adjusted EBITDA per metric ton was $46, up from $44 in third quarter 2013 and up from $36 in fourth quarter 2012. Days working capital remained at record lows, improving by 5 days compared with fourth quarter 2012.
