Fair Value Of Financial Instruments [Abstract]

Fair Value Of Financial Instruments

NOTE 5 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts of cash and equivalents, accounts receivable and accounts payable approximate fair value due to the short-term nature of these instruments. Since our other financial assets and liabilities are not traded in an open market, we use a present value technique, which is a level 3 input, as defined in ASC 825-10, "Financial Instruments," to measure the fair value of these financial instruments. 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 at September 30, 2011, in thousands are as follows:

	Carrying Amount			Estimated Fair Value
Promissory notes	$	2,750		$	2,714
Zero-coupon promissory notes		230			226
Debentures		549			570
Senior promissory notes		1,758			1,825
Long-term promissory notes		1,800			1,832
Less: unamortized discount		(465	)		—
Net liabilities	$	6,622		$	7,167
