Pension Benefits

We sponsor multiple defined benefit pension plans that covered certain workers under collective bargaining contracts. However, as a result of prior-years’ restructuring activities, for all periods presented, 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 income for our pension plans:
