[1]Geographic information for revenues is based upon countries into which product is sold.[2]We use segment adjusted EBITDA as the measure of each segment’s profit or loss. We believe that segment adjusted EBITDA more accurately reflects what the chief operating decision maker uses to make decisions about resources to be allocated to the segments and assess their financial performance. Segment adjusted EBITDA is defined as net income of Huntsman Corporation or Huntsman International, as appropriate, before interest, income tax, depreciation and amortization, net income attributable to noncontrolling interests and certain Corporate and other items, as well as eliminating the following adjustments: (a) business acquisition and integration expenses and purchase accounting inventory adjustments; (b) fair value adjustments to Venator investment, net; (c) certain legal and other settlements and related expenses; (d) costs associated with the Albemarle Settlement, net; (e) loss on sale of business/assets; (f) income from transition services arrangements; (g) certain nonrecurring information technology project implementation costs; (h) amortization of pension and postretirement actuarial losses; (i) restructuring, impairment, plant closing and transition credits (costs); and (j) income from discontinued operations, net of tax.[3]Corporate and other costs, net includes unallocated corporate overhead, unallocated foreign currency exchange gains and losses, LIFO inventory valuation reserve adjustments, nonoperating income and expense and gains and losses on the disposition of corporate assets.[4]Includes costs associated with transition activities related primarily to our Corporate program to optimize our global approach to leverage shared services capabilities.
