◆ the workforce under management includes the current workforce and suspended contracts as of 31 December; ◆ the proportion of women is calculated on the basis of permanent and fixed-term contracts at 31 December; ◆ employees whose contracts terminated on 31 December N are accounted for in the workforce as at 31 December N, as well as in departures during year N;

◆ the number of training hours is calculated for permanent and fixed-term employees. The average number of hours of training per employee is calculated by dividing the total number of training hours by the average workforce in number of people (and not in full-time equivalents); ◆ the proportion of employees trained is calculated by dividing the number of employees trained (counted only once) by the average headcount (in number of people).

CONSOLIDATION AND INTERNAL CONTROL

Each entity is responsible for the data it provides, as is the division responsible for the consolidation of the indicator published: ◆ social data is collected by the Human Resources Division. For Aéroports de Paris, the main source is the human resources information system, fed by the SAP-HR management application. The other systems used are SAPFI - parent company and consolidated financial statements and applications specific to occupational safety. The subsidiaries each have their own HR information systems. Data is integrated directly for each of the companies making up the Group, without intermediate consolidation, via the financial consolidation tool. The data are audited and verified by the Group Human Resources Division;

◆ environmental data is collected, checked, consolidated and validated at the level of each airport department by the environmental manager then consolidated by the sustainable development and public affairs department. During consolidation, consistency checks are performed on the data. Comparisons with results from previous years are made. Differences considered significant are subject to analysis and further processing. The most sensitive and most relevant data are controlled internally and monitored by the Executive Committee should any decisions need to be made. Any deviation from these methods is explained in the reporting protocol and during the reporting exercise.
