Components of Net Periodic Pension Benefit Cost |
Components of Net Periodic Pension Benefit Cost | Note G — Components of Net Periodic Pension Benefit Cost Prior to January 1, 1999, we maintained a defined benefit pension plan for which most of our employees were eligible. We elected to freeze benefits under this defined benefit pension plan as of December 31, 1998. In 1994, we adopted a non-qualified, unfunded, supplemental pension plan covering certain employees, which provides for incremental pension payments so that total pension payments equal those amounts that would have been payable from our principal pension plan if it were not for limitations imposed by income tax regulations. The benefits under this supplemental pension plan continue to accrue as if the principal pension plan had not been frozen. Net pension cost for both plans included the following components:
|  | Three Months Ended June 30, |
In thousands |  | 2013 |  | 2012 |
Service cost |  | $ | 86 |  | $ | 117 |
Interest cost |  | 1,809 |  | 1,960 |
Expected return on plan assets |  | (1,846 | ) | (1,683 | )
Amortization of prior service cost |  | 0 |  | 1 |
Recognized actuarial loss |  | 1,672 |  | 1,500 |
Net periodic benefit cost |  | $ | 1,721 |  | $ | 1,895 |
|  | Six Months Ended June 30, |
In thousands |  | 2013 |  | 2012 |
Service cost |  | $ | 171 |  | $ | 233 |
Interest cost |  | 3,618 |  | 3,920 |
Expected return on plan assets |  | (3,691 | ) | (3,366 | )
Amortization of prior service cost |  | 0 |  | 2 |
Recognized actuarial loss |  | 3,344 |  | 3,000 |
Net periodic benefit cost |  | $ | 3,442 |  | $ | 3,789 |
We made contributions to our funded, frozen pension plan of $2.3 million in the first half of 2013. We plan to make additional contributions of $2.3 million to this pension plan during the remainder of 2013. These contributions to our funded, frozen pension plan are being made in order to obtain the Pension Protection Act of 2006 full funding limit exemption. We are not required to make and do not intend to make any contributions to our unfunded, supplemental pension plan in 2013 other than to the extent needed to cover benefit payments. We expect benefit payments under this supplemental pension plan to total $1.5 million in 2013.
