Exclusion of special items permits evaluation and comparison of results for the Company’s core  business operations, and it is on this basis that management internally assesses the Company’s performance. Exclusion of the Harsco Infrastructure Segment from 2013 provides a basis for comparison of ongoing  operations and prospects since the segment was divested in the fourth quarter of 2013. These measures should be considered in addition to, rather than as a substitute for, other information provided in accordance  with U.S. GAAP. (a) Harsco Metals & Minerals Segment charges primarily attributable to site exit costs and non-cash long lived asset impairment charges associated with strategic actions from Project Orion’s focus on  underperforming contracts (Full year 2014 $50.1 million pre-tax). (b) Harsco Metals & Minerals Segment charges incurred in connection with the termination of a contract for a customer in receivership (Full year 2014 $11.6 million pre-tax, which includes $7.7 million  primarily for non-cash long lived asset impairment and $3.9 million pre-receivership receivable bad debt reserve charges). (c) Brazilian labor claim reserve adjustments in the Harsco Metals & Minerals Segment (Full year 2014 $7.5 million pre-tax). (d) Harsco Metals & Minerals Segment Improvement Plan (“Project Orion”) restructuring charges (Full year 2014 $12.0 million pre-tax). (e) Loss resulting from the Harsco Infrastructure Transaction, which was consummated in the fourth quarter of 2013 (Full year 2014 $3.9 million pre-tax; Full year 2013 $271.3 million pre-tax). (f) Strategic transaction review costs recorded as Corporate expenses (Full year 2014 $3.5 million pre-tax).

(k) Bad debt expense incurred in the Harsco Metals & Minerals Segment (Full year 2013 $2.6 million pre-tax). (l) Depreciation expense reduction from classification of Harsco Infrastructure Segment assets as held-for-sale (Full year 2013 $17.3 million pre-tax). (m) Includes equity in income of affiliates and noncontrolling interests (Full year 2013 $(2.9) million). Segment operating results incorporate reclassifications for the three months and twelve months ended December  31, 2013 to conform to the revised manner in which the Company now allocates corporate expenses to operating segments as a result of changes in organizational structure resulting from the Infrastructure  Transaction, which was consummated in the fourth quarter of 2013. The changes do not impact the Company’s previously reported consolidated revenues from continuing operations, operating income from  continuing operations or income from continuing operations before income taxes and equity income.
