Long-Term Debt [Abstract]
Long-Term Debt	Note 4 – Long-Term Debt At September 30, 2011 and June 30, 2011, we had an unsecured revolving credit facility under which we may borrow up to a maximum of $160 million at any one time, with the potential to expand the total credit availability to $260 million based on obtaining consent of the issuing bank and certain other conditions. The facility expires in October 2012, and all outstanding amounts are then due and payable. At September 30, 2011 and June 30, 2011, we had no borrowings outstanding under this facility. Loans may be used for general corporate purposes. At September 30, 2011, we had approximately $6.7 million of standby letters of credit outstanding, which reduced the amount available for borrowing on the unsecured revolving credit facility. We paid no interest for the three months ended September 30, 2011 and 2010. The facility contains certain restrictive covenants, including limitations on indebtedness, asset sales and acquisitions. There are two principal financial covenants: an interest expense test that requires us to maintain an interest coverage ratio not less than 2.5 to 1 at the end of each fiscal quarter; and an indebtedness test that requires us to maintain a leverage ratio not greater than 3 to 1 at all times. The interest coverage ratio is calculated by dividing Consolidated EBIT (as defined more specifically in the credit agreement) by Consolidated Interest Expense (as defined more specifically in the credit agreement), and the leverage ratio is calculated by dividing Consolidated Debt (as defined more specifically in the credit agreement) by Consolidated EBITDA (as defined more specifically in the credit agreement). At September 30, 2011 and June 30, 2011, we were in compliance with all applicable provisions and covenants of the facility, and we met the requirements of the financial covenants by substantial margins. We currently expect to remain in compliance with the facility's covenants for the foreseeable future. At September 30, 2011, we were not aware of any event that would constitute a default under the facility.
