Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt At December 31, 2015 and June 30, 2015, we had an unsecured credit facility (“Facility”) 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 subject to us 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. When we have outstanding borrowings under this Facility, they will be classified as long-term debt due to the long-term nature of this Facility. At December 31, 2015 and June 30, 2015, we had no borrowings outstanding under this Facility. At December 31, 2015, we had $4.7 million of standby letters of credit outstanding, which reduced the amount available for borrowing on the Facility. We paid no interest for the three and six months ended December 31, 2015 and 2014. 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).
