Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract] |
RETIREMENT BENEFIT PLANS | RETIREMENT BENEFIT PLANS The Company maintains defined benefit pension plans that cover employees in its manufacturing plants located in Andover, United Kingdom (the “UK Plan”) and Tuttlingen, Germany (the “Germany Plan”). The Company closed the Tuttlingen, Germany plant in December 2005. The Company did not terminate the Germany Plan, and the Company remains obligated for the accrued pension benefits related to this plan. Effective March 31, 2011, the Company froze the benefits due to the participants of the UK Plan in their entirety; this curtailment resulted in a $0.3 million reduction in the projected benefit obligations which the Company recorded on that date. The plans cover certain current and former employees. Net periodic benefit costs for the Company’s defined benefit pension plans included the following amounts:
| Three Months Ended March 31, |
| 2014 |  | 2013 |
| (In thousands)
Interest cost | $ | 163 |  |  | $ | 137 |  |
Return on plan assets | (134 | ) |  | (100 | ) |
Net period benefit cost | $ | 29 |  |  | $ | 37 |  |
The Company made $0.3 million and $0.2 million of contributions to its defined benefit pension plans during the three months ended March 31, 2014 and 2013, respectively.
