Postretirement Medical and Life Insurance Benefit Plans

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. At the end of the year, we discount our plan liabilities using an assumed discount rate. In estimating this rate, we, along with our third-party actuaries, review bond indices, consider yield curve analysis results and the past history of discount rates.

The actuarial present value of benefit obligations summarized below was based on the following assumption:


	2012	2011
Weighted-average assumption as of June 30
Discount rate.................................................................................................	3.78%	5.29%

The net periodic benefit costs were determined utilizing the following beginning-of-the-year assumptions:


	2012	2011	2010
Discount rate.........................................................................	5.29%	5.21%	6.34%
Health care cost trend rate.................................................	10.00%	10.00%	10.00%
