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 March 31		Nine Months Ended March 31
	2012	2011	2012	2011
Components of net periodic benefit cost
Service cost......................................................................	$ 6	$ 6	$ 18	$ 18

Amortization of prior service asset..............................	(1)	(1)	(3)	(3)
Net periodic benefit cost............................................	$ 34	$ 27	$ 102	$ 81

For the three and nine months ended March 31, 2012, we made approximately $40,000 and $106,000, respectively, in contributions to our postretirement medical and life insurance benefit plans. We expect to make approximately $0.1 million more in contributions to our postretirement medical and life insurance benefit plans during the remainder of 2012.
