[1] The Global Operations segment derives substantially all of its revenues, and thus its operating results, from intersegment activities.

[2] 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 individ ual operating segments are done at the beginning of the year based on budgeted amounts. Any differences between actual and budgeted amounts are reflected in Corporate and eliminations. Furthermore, Corporate and eliminations includes elimination of inter-c ompany income statement transactions. One such example includes licensing and service arrangements with affiliates. Payments received in advance from affiliates are recognized as revenue and eliminated in consolidation as earned and payment becomes assure d over the life of the contract. During 2018 , 2017 and 201 6 , affiliate licensing and service fees of $338,304, $298,693 and $283,078, respectively, that were received in 2017, 2016 and 2015, respectively, were recognized as revenue and eliminated in consoli dation. Corporate and eliminations also includes the elimination of inter-company balance sheet amounts .
