Note 6 – Postretirement Benefits

We and certain of our operating subsidiaries provide multiple postretirement medical and life insurance benefit plans. We recognize the cost of benefits as the employees render service. Postretirement benefits are funded as incurred.

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


	Three Months Ended September 30
	2011	2010
Components of net periodic benefit cost
Service cost	$ 6	$ 6
Interest cost	37	34
Amortization of unrecognized net gain	(8)	(12)
Amortization of prior service asset	(1)	(1)

Net periodic benefit cost	$ 34	$ 27

For the three months ended September 30, 2011, we made approximately $36,000 in contributions to our postretirement medical and life insurance benefit plans. We expect to make approximately $0.2 million more in contributions to our postretirement medical and life insurance benefit plans during the remainder of 2012.
