Fair Value of Financial Instruments [Abstract]

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. 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 March 31, 2013, are as follows (in thousands):

	Carrying			Estimated
	Amount			Fair Value
Promissory notes	$	2,880		$	2,853
Zero-coupon promissory notes		230			225
Debentures		537			534
Senior promissory notes		1,771			1,770
Long-term promissory notes		125			121
Less: unamortized discount		(39	)		—
Net liabilities	$	5,504		$	5,503

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, promissory notes payable with a carrying value of $3,000,000 are excluded from the table above.
