Pension Benefits [Abstract] |
Pension Benefits | Note 5 – Pension Benefits We and certain of our operating subsidiaries have sponsored multiple defined benefit pension plans covering union workers at certain locations. As a result of restructuring activities in recent years, we no longer have any active employees continuing to accrue service cost or otherwise eligible to receive plan benefits. Benefits being paid under the plans are primarily based on negotiated rates and years of service. We contribute to these plans at least the minimum amount required by regulation. The following table summarizes the components of net periodic benefit cost for our pension plans:
|  | Three Months Ended March 31 |  | Nine Months Ended March 31
|  | 2012 |  | 2011 |  | 2012 |  | 2011
| Components of net periodic benefit cost |  |  |  |  |  |  |
| Interest cost................................................................ | $ 483 |  | $ 487 |  | $ 1,449 |  | $ 1,461
| Expected return on plan assets............................... | (599) |  | (507) |  | (1,797) |  | (1,521)
| Amortization of unrecognized net loss................. | 89 |  | 136 |  | 267 |  | 410
| Net periodic benefit (income) cost..................... | $ (27) |  | $ 116 |  | $ (81) |  | $ 350
For the three and nine months ended March 31, 2012, we made pension plan contributions totaling zero and approximately $1.0 million, respectively. We do not expect to make any further contributions to our pension plans during the remainder of 2012.
