Defined Benefit Pension Plans

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, at June 30, 2011 there were no 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.

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:

	2011	2010
Weighted-average assumption as of June 30
Discount rate	5.29%	5.21%

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

	2011	2010	2009
Discount rate	5.21%	6.34%	6.65%
Expected long-term return on plan assets	7.00%	8.00%	8.00%

In determining the long-term expected return on plan assets, we consider our related investment guidelines, our expectations of long-term rates of return by asset category, our target asset allocation weighting and historical rates of return and volatility for equity and fixed income investments. The investment strategy for plan assets is to control and manage investment risk through diversification among asset classes, investment managers/funds and investment styles. The plans' investment guidelines have been designed to meet the intended objective that plan assets earn at least nominal returns equal to or in excess of the plans' liability growth rate. In consideration of the current average age of the plans' participants, the investment guidelines are based upon an investment horizon of at least 10 years.

The target and actual asset allocations for our plans at June 30 by asset category are as follows:


	Target Percentage of Plan Assets at June 30	Actual Percentage of Plan Assets
	2011	2011	2010
Cash and equivalents	0-10%	1%	2%
Equity securities	30-70%	50%	54%
Fixed income	30-70%	49%	44%
Total		100%	100%

Our target asset allocations are maintained through ongoing review and periodic rebalancing of equity and fixed income investments with assistance from an independent outside investment consultant. Also, the plan assets are diversified among asset classes, asset managers or funds and investment styles to avoid concentrations of risk. We expect that a modest allocation to cash will exist within the plans, because each investment manager is likely to hold limited cash in a portfolio.
