Backlog consists of the estimated revenue attributable to the uncompleted portion of lump-sum engineering, procurement and construction contracts and variation orders plus, with regard to engineering services and facilities management contracts, the estimated revenue attributable to the lesser of the remaining term of the contract and, in the case of life-of-field facilities management contracts, five years. The group uses this key performance indicator as a measure of the visibility of future earnings. Backlog is not an audited measure. Other companies in the oil & gas industry may calculate this measure differently.
EBITDA means earnings before interest, tax, depreciation, amortisation and impairment and is calculated as profit before tax and net finance income adjusted to add back charges for depreciation, amortisation and impairment charges (as per note 3 to the interim condensed consolidated financial statements).
Profit for the period attributable to Petrofac Limited shareholders, excluding the gain on the EnQuest demerger in April 2010.
