FAIR VALUE OF FINANCIAL INSTRUMENTS [Abstract]

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 December 31, 2018 and September 30, 2018.  See Note 10 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.
