|in million €||2017||2016|
|Wages and salaries||5,481.8||5,024.6|
|Social security, pension plans and other employee benefit costs||1,253.5||1,137.1|
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).
|Part-time employees and marginal part-time workers||117,430||110,907|
The increase in the employee headcount was due primarily to the inclusion of the Supermärkte Nord companies for the full year and the first-time inclusion of REWE Dortmund SE & Co. KG, Dortmund (see note 4 "Acquisitions").
