Breakdown of Personnel Expenses
in million €20172016
Wages and salaries5,481.85,024.6
Social security, pension plans and other employee benefit costs1,253.51,137.1

The increase in personnel expenses is essentially attributable to the inclusion of the Supermärkte Nord companies for the entire year, additions to the scope of consolidation resulting from this year’s acquisitions (see note 4 “Acquisitions”) and the 2017 pay scale increase.

The interest cost on provisions for employee benefits (see note 33 "Employee Benefits") is not reported under expenses for pension plans, but under interest result as the net interest expense from defined benefit plans.

Expenses of 505.4 million euros (previous year: 486.8 million euros) were incurred for defined contribution plans in the financial year. The employer's contribution to statutory pension insurance totalled 488.5 million euros (previous year: 471.4 million euros).
