Segment Information Our Chief Operating Decision Maker evaluates segment operating performance using segment operating income. Segment operating income is defined as GAAP operating income excluding intangible amortization and amortization of fair value step-ups of inventory and fixed assets from acquisitions completed subsequent to December 31, 2011, the impact of restructuring related inventory write-offs, impairment charges and special charges or gains. The Company also refers to this measure as adjusted operating income. The Company uses this measure because it helps management understand and evaluate the segments core operating results and facilitate comparison of performance for determining incentive compensation achievement. We organize our reporting structure into three segments: Energy, Aerospace &amp; Defense and Industrial.
