Long-Term Debt	3 Months Ended

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt At September 30, 2013 and June 30, 2013, we had an unsecured credit agreement under which 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 facility 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 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 September 30, 2013 and June 30, 2013, we had no borrowings outstanding under this facility. At September 30, 2013, we had approximately $3.7 million of standby letters of credit outstanding, which reduced the amount available for borrowing under the credit agreement. We paid no interest for the three months ended September 30, 2013 and 2012. At September 30, 2013 and June 30, 2013, we were in compliance with all applicable provisions and covenants of this facility, and we exceeded the requirements of the financial covenants by substantial margins. At September 30, 2013, we were not aware of any event that would constitute a default under the facility. 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 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 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).
