We define segment earnings as income (loss) before interest expense, interest income, other operating (expense) income, other income (expense) and income taxes and include the earnings of non-consolidated affiliates in segment results consistent with management's monitoring of the operating segments.
CHLOR ALKALI PRODUCTS
Chlor Alkali Products sales for the fourth quarter of 2013 were $322.2 million compared to $336.4 million in the fourth quarter of 2012. Lower selling prices more than offset higher sales volumes.

Fourth quarter 2013 Chlor Alkali segment earnings declined from $54.3 million in the fourth quarter of 2012 to $30.7 million in the fourth quarter of 2013. The year-over-year decline in segment earnings reflects lower ECU netbacks which more than offset increased shipments of chlorine, hydrochloric acid, bleach and potassium hydroxide.
