[2] Unallocated corporate expenses primarily comprise corporate administrative expenses (e.g., corporate finance, legal, human resources, information systems, deferred compensation and environmental remediation) that are not included in segment operating income and not used to evaluate segment performance.

[3] The changes in unallocated corporate assets between 2013 and 2015 were primarily attributable to changes in the balance of U.S. cash and cash equivalents, which are not allocated to segments.
