Revenue growth on a like‐for‐like basis (i.e. organic growth)

Growth on a like‐for‐like basis (and constant exchange rate) is calculated excluding the effects of exchange rate variations and the variations of the consolidation scope on a chosen period.

Exchange rate impacts are measured by converting the revenue of the period with the average exchange rate from the previous period.

Scope variation impacts are measured excluding acquisitions, revenue of the period and for transfers, revenue of the previous period, in order to create a scope which is identical to the previous period. This alternative measure enables to identify the real performance of the Group in terms of activity on the chosen period.
