FAIR VALUE OF FINANCIAL INSTRUMENTS [Abstract]  
Schedule of Fair Value of Financial Instruments
The following table presents financial instruments, other than long-term debt, that we measured at fair value on a recurring basis at June 30, 2015 and September 30, 2014.  See Note 7 for a detailed discussion of our long-term debt.  We have classified the following assets and liabilities in accordance with the fair value hierarchy set forth in the applicable standards.  In instances where the inputs used to measure the fair value of an asset fall into more than one level of the hierarchy, we have classified them based on the lowest level input that is significant to the determination of the fair value.
