20 Average number of employees and personnel costs
|Civil servants (domestic, active service relationship)||15,781||17,472||19,179|
|Trainees and students on cooperative degree courses||6,559||7,510||7,942|
|Personnel costs||millions of €||15,504||16,463||15,856|
The average headcount decreased by 1.9 percent compared with the prior year. This trend is largely attributable to a lower average domestic headcount, which was down by 4.3 percent. Staff restructuring measures in the Germany operating segment and the Group Headquarters & Group Services segment in particular contributed to this trend. In addition, Strato AG was deconsolidated from the Group Development operating segment as of March 31, 2017.
Outside of Germany, the average number of employees increased in total slightly by 0.4 percent due to staff increases both in the United States and the Europe operating segments as well as in the Group Headquarters & Group Services segment.
Personnel costs decreased by 5.8 percent year-on-year, due to the high restructuring expenses in connection with the early retirement arrangements for civil servants in the prior year and the lower average headcount in Germany. By contrast, higher average salaries of employees resulted in an increase in personnel costs.
