Reformulation of information presented

The consolidated information reflected in this report may display significant variations in terms of comparability, because of the wider scope of coverage. Especially significant was the incorporation of BAA's data, which was not reported in the 2006 report, and the greater amount of information from Swissport that has been incorporated.

The principles in GRI3 and the AA1000AS Standard were used as the basis for information presentation, which is why there are more indicators this year and an absence of several indicators related to historical data.
