The Company’s Chief Operating Decision Maker (“CODM”) is the President and Chief Executive Officer. The CODM is responsible for allocating resources and assessing performance based on the segment’s operating profit or loss, among other considerations. Segment operating profit is net sales less cost of sales and other operating expenses, excluding interest expense, equity-based compensation, non-service pension expense and other corporate expenses. Cost of sales and other operating expenses are directly attributable to the respective segment or allocated on the basis of sales, headcount or profit. Long-lived tangible assets and total asset information by segment is not provided to or reviewed by our CODM as it is not used to make strategic decisions, allocate resources, or assess performance.

We report results to our CODM under our four segments identified as Space and Defense, Military Aircraft, Commercial Aircraft and Industrial. Disaggregation of operating results by segment and reconciliations to consolidated amounts are as follows:
