(€ in thousands)
Social security costs
- Other personnel expenses include costs of secondary benefits such as health insurance, vehicle lease costs, sales commissions and bonuses.
The average number of employees in 2014 was 3,888 (2013: 3,491) spread across the following functional areas:
Research and development
Sales, general and administrative
At 31 December 2014, the group had 4,172 (2013: 3,671) employees. During 2014, 2,797 of employees worked outside the Netherlands (2013: 2,351).
The group's pension plans primarily comprise of defined contribution plans, limiting the employer's legal obligation to the amount it agrees to contribute during the period of employment and a defined benefit plan for a German subsidiary. This defined benefit plan is unfunded and has no plan asset. Management is of the opinion that the plan has limited risks to the group as it was frozen in 2007. In the extraordinary event that the group is unable to meet its obligations, the participants will receive (partial) payments from a state-owned pension protection fund.
The total pension costs of €7.8 million consist of the costs of the defined contribution plans of €7.5 million (2013: €7.6 million) and of the German-defined benefit plan of €0.3 million (2013: €0.2 million).
The movement of the German-defined benefit obligation is presented below:

PRESENT VALUE OF OBLIGATION AS AT 1 JANUARY
Current service cost
- Experience losses / (gains) due to change in demographical assumptions
- Losses / (gains) from change in financial assumptions
PRESENT VALUE OF OBLIGATION AS AT 31 DECEMBER
The service cost and the interest cost are recognised as pension costs, while the actuarial (gains)/losses are credited/charged to 'Other comprehensive income'.
The significant actuarial assumptions were as follows:
Average life expectancy1
- The above average life expectancy is the average actual value for males and females retiring at age 65 set in accordance with the common German mortality tables 'Heubeck 2005 G'.
A 0.1% increase or decrease in discount rate would result in a decrease or increase in the defined benefit obligation of approximately €0.1 million and a 1-year increase or decrease in average life expectancy would result in a €0.1 million increase or decrease in the defined benefit obligation.
In Italy, employees are paid a leaving indemnity on termination of their employment. This is a statutory payment based on Italian civil law. An amount is accrued each year based on the employee's remuneration and previously revalued accruals. The indemnity has the characteristics of a defined contribution obligation and is an unfunded, but fully provided liability.
Employees in the United States are offered the opportunity to participate in the 401K pension plan, which involves no contribution or obligation from the group besides withholding and paying the employee's contribution.
For defined contribution plans, the group pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The group has no further payment obligations once the contributions have been paid. The contributions are recognised as employee benefit expenses when service has been rendered to the group. Prepaid contributions are recognised as an asset to the extent that a cash refund or reduction of future payments is available.
In relation to the defined benefit plan, the group recognised a liability on the balance sheet based on the present value of the defined benefit obligation at the end of the reporting period. The defined benefit obligation is calculated annually using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and which have terms to maturity approximating to the terms of the related pension obligation.
Service costs and interest costs are charged to the pension expenses. Actuarial gains and losses are charged or credited to equity in 'Other comprehensive income' in the period in which they arise.
