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 or contract.

The following table summarizes the components of net periodic benefit cost for our pension plans:


	Three Months Ended December 31						Six Months Ended December 31


		2011			2010			2011			2010
Components of net periodic benefit cost
Interest cost	$	483		$	487		$	966		$	974
Expected return on plan assets		(599	)		(507	)		(1,198	)		(1,014	)
Amortization of unrecognized net loss		89			137			178			274
Net periodic benefit (income) cost	$	(27	)	$	117		$	(54	)	$	234

For the three and six months ended December 31, 2011, 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.
