(1) During the first six months of 2013, our Chemical Business experienced downtime at the Cherokee, El Dorado and Pryor Facilities resulting in lost production and significant adverse effect on operating results. During the first six months of 2012, our Chemical Business also experienced downtime at the El Dorado and Pryor Facilities that adversely affected operating results. Also see Note 12—Property and Business Interruption Insurance Claims and Recoveries.

(2) Gross profit by business segment represents net sales less cost of sales. Gross profit classified as “Other” relates to the sales of industrial machinery and related components.

(3) Our chief operating decision makers use operating income by business segment for purposes of making decisions, which include resource allocations and performance evaluations. Operating income by business segment represents gross profit by business segment less selling, general and administrative expense (“SG&A”) incurred by each business segment plus other income and other expense earned/incurred by each business segment before general corporate expenses and other business operations, net. General corporate expenses and other business operations, net, consist of unallocated portions of gross profit, SG&A, other income and other expense.

(4) The amounts included are not allocated to our Climate Control and Chemical Businesses since these items are not included in the operating results reviewed by our chief operating decision makers for purposes of making decisions as discussed above. A detail of these amounts are as follows:
