- Definition Segment EBITDA includes revenue and expenses that are controllable by the segment. Corporate and administrative expenses are allocated to the segments based on usage, with shared expenses apportioned based on the segment's percentage of consolidated revenue. Segment EBITDA excludes restructuring and acquisition related expenses, depreciation, amortization, interest, change in fair value of contingent consideration liabilities, taxes and equity in earnings of unconsolidated subsidiaries. Loss on debt extinguishment is considered a component of interest in calculating EBITDA, as the write-off of debt issuance costs is similar to the treatment of debt issuance cost amortization. + References No definition available. + Details
