Operating profit

The performance of the operating activities in the first half of 2015, both in absolute terms and on a homogeneous basis compared with the same period of the previous year, was not affected by unusual occurrences extraneous to the production cycle. The operating profit achieved in the period reviewed in this Report reflects in a substantially consistent fashion the evolution of the production activities described in the comments to the item “Revenue”. The period's margin is 5.8% (5.3%). The effects of the Purchase Price Allocation that regard the acquisition of the Impregilo Group, which occurred during 2013, amount to € 6.2 million and are mainly represented by the amortizations of intangible assets.

The overhead costs for the central corporate units and the other general expenses, for the period reviewed in this report, totalled approximately € 61.0 million (roughly € 75.1 million).
