Note C – Fair Value of Financial Instruments

The carrying amounts of variable rate notes payable to the banks and the variable rate mortgage payable approximate fair value as of December 31, 2013 and 2012 because these notes reflect market changes to interest rates. The fair value of the subordinated convertible debt approximates its principal amount of $12 million at December 31, 2013 and 2012, which exceeds its carrying amount as a result of the unamortized discount related to the bifurcation of the embedded conversion option. The carrying amount of the advance to supplier approximates its fair value at December 31, 2013 and 2012. Fair value of financial instruments are based on level 2 inputs. Derivative financial instruments are carried at fair value (see Note B [12]).
