Fair Value of Financial Instruments

NOTE 6 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts of cash, accounts receivable and accounts payable approximate their estimated fair value due to the short-term nature of these instruments. Since our other financial liabilities are not traded in an open market, we generally use a present value technique, which is a level 3 input, as defined in generally accepted accounting principles, to measure the estimated fair value of these financial instruments, except for valuing stock options and warrants (see Note 7 below). The rate used for discounting expected cash flows is a risk-free rate adjusted for systematic and unsystematic risk.

The carrying amounts and estimated fair values of these financial instruments (all are liabilities) at June 30, 2013, are as follows (in thousands):

 

     Carrying     Estimated  
     Amount     Fair Value  

Notes Payable

   $ 2,705      $ 2,660   

Zero-coupon notes

     230        224   

Debentures

     537        479   

Senior notes

     1,771        1,761   

Long-term notes

     225        221   

Less unamortized discount

Net liabilities

   $ 5,318      $ 5,345   
  

 

 

   

 

 

 

Due to the inherent nature of related party transactions, we have not attempted to estimate the fair value of liabilities payable to related parties of the Company. As such, related party notes payable with a carrying value of $3,000,000 are excluded from the table above.

 

We may be obligated to issue shares under a redemption provision within the Revolving Credit Facility (see Note 3). The redemption provision constitutes a put option for which we calculated a fair value at the issuance of the Revolving Credit Facility and recorded the value as a component of other accrued expenses on our balance sheet. We valued the put option using the Black Scholes options pricing model, a level 3 input, using a risk free interest rate, estimated volatility of our stock price, an estimated term, and expected dividend yield. At each reporting date, we revalue the put option using the same pricing model.
