Like-for-like Growth Rates

The like-for-like growth rates of revenues and orders are calculated by adjusting reported revenues and orders, in both the current and comparable periods, for the effects of currency translation and portfolio changes. The adjustment for portfolio changes is calculated as follows: where the results of any business acquired or divested have not been consolidated and reported for the entire duration of both the current and comparable periods, the reported revenues and orders of such business are adjusted to exclude the revenues and orders of any corresponding quarters which are not comparable when computing the like-for-like growth rate. In addition, certain other adjustments, which affect the business portfolio but do not qualify as a divestment, are treated in a similar manner to a divestment. We do not adjust for portfolio changes where the business acquired or divested has annual revenues of less than $50 million.
