Pension Benefits

We sponsor multiple defined benefit pension plans that have covered certain union workers. 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:

	Three Months Ended   September 30,

Components of net periodic benefit income

Expected return on plan assets	(614		)	(595		)
Amortization of unrecognized net loss	115			172
Net periodic benefit income	$	(61	)	$	(15	)

For the three months ended September 30, 2013, we made no pension plan contributions and we expect to make no contributions to our pension plans during 2014.
