In the first quarter of 2015, as part of the acquisition of Arlon, we acquired the Hourly Employees Pension Plan of Arlon, LLC, Microwave Materials and Silicone Technologies Divisions, Bear, Delaware. This plan covers Arlon union employees and was frozen to new participants and accumulating benefits in 2006. As of the acquisition date, January 22, 2015, the funded status of the plan was a liability of approximately $2.0 million. We have recorded this as part of our long term pension liability within our condensed consolidated statements of financial position.

In the first quarter of 2014, we made a one-time cash payment to a former employee of $0.8 million in accordance with the provisions of his retirement contract related to his participation in the Company's Pension Restoration Plan. This payment resulted in a settlement charge of approximately $0.1 million, which was recognized in the first quarter of 2014.

Employer Contributions

In the second quarters of 2015 and 2014, we made voluntary contributions of $6.5 million and $6.5 million, respectively to our qualified defined benefit pension plans. These are the only amounts contributed in the first nine months of 2015 and 2014.

We did not make any contributions to our non-qualified defined benefit pension plan for the nine months ended September 30, 2015. We made $0.8 million in contributions to our non-qualified defined benefit pension plan for the quarter ended March 31, 2014. This was the only amount contributed in the first nine months of 2014.
