Fair Value Measurements

Fair Value Measurements

13.   Fair Value Measurements

Effective January 1, 2008, the Company adopted ASC 820, “Fair Value Disclosure and Measurements” (“ASC 820”), for the financial assets and liabilities and nonfinancial assets and liabilities which are measured at fair value on a recurring (annual) basis.  ASC 820 establishes a framework for measuring fair value in the form of a fair value hierarchy which prioritizes the inputs into valuation techniques used to measure fair value into three broad levels.  This hierarchy gives the highest priority to quoted prices (unadjusted) in active markets and the lowest priority to unobservable inputs.  Further,  financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement.  The three levels of the fair value hierarchy per ASC 820 are as follows:

Level 1:  Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2:  Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

Level 3:  Unobservable inputs due to the fact that there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

The following table summarizes the Company’s financial assets at fair value at September 30, 2011, by respective level of the fair value hierarchy:

	Level 1		Level 2		Level 3		Total
	(in thousands)
Assets:
Cash equivalents	$	54,979	$	—	$	—	$	54,979
Short-term available for sale securities	21		—		—		21
Warrant to purchase common stock	—		2		—		2
Long term account receivable	—		—		643		643
	$	55,000	$	2	$	643	$	55,645

The Company’s cash equivalents, comprised principally of U.S. treasury securities, are classified within Level 1 of the fair value hierarchy.

The Company’s short-term available for sale securities are classified within Level 1 of the fair value hierarchy and are comprised of common stock, which have been valued using quoted prices in active markets.

The Company’s warrant to purchase common stock is classified within Level 2 of the fair value hierarchy. The fair value of the warrant to purchase common stock was determined using a Black-Scholes model with inputs based on quoted market price, historic volatilities, risk free interest rates and the life of the warrant.

The Company’s long term receivable is classified within Level 3 of the fair value hierarchy.  The long term receivable is related to the sale of a subsidiary to Apogee as discussed in Note 8, and is comprised of cash and common shares.  The receivable is due and payable in July 2012 and is subject to a number of risks including market risk, performance risk and certain exchange related restrictions on the stock component.  In addition to certain observable inputs including quoted market price, historic volatilities, risk free interest rates, the Company also used estimated discount rates to reflect the credit risks associated with the receivable.
