Fair Value of Financial Instruments
 
The Company uses the standard that defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties.  The carrying value of all financial instruments classified as current assets or liabilities is deemed to approximate fair value because of the short term nature of these instruments and the interest rate applicable to the Company's financial status. Based on the current estimated market rates at December 31, 2011, the fair value of the non-current debt approximates its carrying value.
