Long-Term Debt [Abstract]
Long-Term Debt	Note 4 – Long-Term Debt At June 30, 2011, we had an unsecured revolving credit facility under which we could 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. On April 18, 2012, we entered into a new unsecured credit agreement (“New Credit Agreement”) with the Lenders named in the New Credit Agreement and JPMorgan Chase Bank, N.A. as Administrative Agent. The New Credit Agreement replaced the facility discussed above. The material terms of the New Credit Agreement are substantially similar to the terms of our previous credit agreement, except with respect to maturity, interest rate margins and fees. The New Credit Agreement provides that we may borrow, on a revolving credit basis, up to a maximum of $120 million at any one time, with potential to expand the total credit availability to $200 million based on obtaining consent of the issuing banks and certain other conditions. The New Credit Agreement expires on April 18, 2017, and all outstanding amounts are then due and payable. Interest is variable based upon formulas tied to LIBOR or an alternative base rate defined in the New Credit Agreement, at our option. We must also pay facility fees that are tied to our then-applicable consolidated leverage ratio. Loans may be used for general corporate purposes. Based on the long-term nature of this facility, when we have outstanding borrowings under this facility, we will classify the outstanding balance as long-term debt. At June 30, 2012 and 2011, we had no borrowings outstanding under these facilities. At June 30, 2012, we had approximately $6.2 million of standby letters of credit outstanding, which reduced the amount available for borrowing under the New Credit Agreement. We paid no interest in 2012 and 2011. At June 30, 2012 and 2011, we were in compliance with all applicable provisions and covenants of these facilities, and we exceeded the requirements of the financial covenants by substantial margins. At June 30, 2012, we were not aware of any event that would constitute a default under the facility. The New Credit Agreement 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 consolidated 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 New Credit Agreement) by Consolidated Interest Expense (as defined more specifically in the New Credit Agreement), and the leverage ratio is calculated by dividing Consolidated Debt (as defined more specifically in the New Credit Agreement) by Consolidated EBITDA (as defined more specifically in the New Credit Agreement.)
