[1] Certain long-term assets, including property, plant and equipment, goodwill and other intangibles, which benefit multiple operating segments, are included in Corporate and Eliminations. Allocations of certain expenses related to these assets to the individual operating segments are done at the beginning of the year based on budgeted amounts. Any differences b etween actual and budgeted amounts are reflected in Corporate and Eliminations because allocations are translated from the US Dollar to local currency at budget rates when recorded, and Corporate and Eliminations also includes the elimination of inter-comp any balance sheet amounts.
