September 24, 2014 CORPORATE

In conjunction with these presentations, the Group is also providing an update on current trading. In the first two months of Q3 2014, underlying revenues increased by 5% organically and adjusted for trading days. So far in September the seasonal pick-up in our business has been slightly weaker than normal, most notably in Germany and France. This reflects some uncertainty in parts of Europe, consistent with the recent softer economic data. In North America, our business is holding up well.

We continue to be very focused on reaching our EBITA margin target of above 5.5% in 2015. Despite the recent softening of the economic environment, a reacceleration of GDP growth is expected for next year. Given this outlook and based on the good progress on our six strategic priorities and our continued price and cost discipline, we remain convinced we will achieve our target.
