Pension Benefits (Policy)	6 Months Ended
Pension Benefits (Policy)	Dec. 31, 2011
Pension Benefits [Abstract]
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.

Disclosure of accounting policy for pension plans. This accounting policy may address (1) the types of plans sponsored by the entity (2) groups that participate in (or are covered by) each plan (3) how plan assets, liabilities and expenses are measured, including the use of any actuaries and (4) significant assumptions used by the entity to value plan assets and liabilities and how such assumptions are derived.
