Performance measures

We evaluate the performance of our divisions primarily based on orders received, revenues, Operational EBITDA and Operational EBITDA as a percentage of Operational revenues (Operational EBITDA margin).

Operational EBITDA represents EBIT excluding depreciation and amortization, restructuring and restructuring-related expenses, adjusted for the following: (i) unrealized gains and losses on derivatives (foreign exchange, commodities, embedded derivatives), (ii) realized gains and losses on derivatives where the underlying hedged transaction has not yet been realized, (iii) unrealized foreign exchange movements on receivables/payables (and related assets/liabilities), (iv) acquisition-related expenses and (v) certain non-operational items.

Operational revenues are total revenues adjusted for the following: (i) unrealized gains and losses on derivatives, (ii) realized gains and losses on derivatives where the underlying hedged transaction has not yet been realized, and (iii) unrealized foreign exchange movements on receivables (and related assets).

See “Note 23 Operating segment and geographic data” to our Consolidated Financial Statements for a reconciliation of Operational EBITDA to EBIT.
