Fair Value Of Financial Instruments

(7)  Fair Value of Financial Instruments:

The following table summarizes the carrying amounts and estimated fair values for long-term debt at March 31, 2017 and December 31, 2016. For the other financial instruments including cash, accounts receivable, long-term debt due within one year, accounts payable and other current liabilities, the carrying amounts approximate fair value due to the relatively short maturities of those instruments.



The fair value of our long-term debt is estimated based upon quoted market prices at the reporting date for those financial instruments.
