Fair Value Measurements

Fair Value Measurements

Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement.

• Level 1 — Quoted prices in active markets for identical assets or liabilities;

• Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

• Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs.

Liabilities Measured at Fair Value on a Recurring Basis

The Company had no liabilities required to be measured at fair value on a recurring basis at September 30, 2013 and December 31, 2012. There were no transfers in or out of either Level 1 or Level 2 fair value measurements during the nine months ended September 30, 2013 and the year ended December 31, 2012. During the nine months ended September 30, 2013 and the year ended December 31, 2012, there were no transfers in or out of the Level 3 hierarchy.

Changes in Level 3 liabilities are as follows (in thousands):

	Nine months ended September 30, 2013		Year ended December 31, 2012
Balance, beginning of period	$	—	$	16,622
Fair value adjustments, net	—		(2,649		)
Reclassification to additional paid-in capital	—		(13,973		)
Net transfers in/(out)	—		—
Balance, end of period	$	—	$	—

On June 14, 2012, provisions in the Company’s Exercisable and Contingent Warrant Certificates were amended to eliminate anti-dilution price adjustment provisions and remove cash settlement provisions of a change of control event. Upon amendment, the warrants met the requirements for classification as equity. All fluctuations in the fair value of the warrant liability prior to June 2012 were recognized as non-cash income or expense items within the statement of operations. The fair value accounting methodology for the warrant liability is no longer required following the contractual amendment.

Fair Value of Other Financial Instruments

The carrying value and estimated fair value of the Company’s marketable securities, convertible notes and long-term debt are as follows (in thousands):

	September 30, 2013				December 31, 2012
	Carrying Value		Fair Value		Carrying Value		Fair Value
Marketable securities	$	220	$	220	$	—	$	—
2008 Notes (1)	—		—		5,133		5,163
Term loan	47,619		47,619		25,000		25,000
Borrowings under revolving credit facility	27,377		27,377		—		—
Capital lease obligations	1,643		1,601		1,784		1,736

(1)The carrying value of the 2008 Notes represents the discounted debt component only, while the fair value of the Notes is based on the market value of the respective notes, including convertible equity features.

The estimated fair value of the 2008 Notes is based upon quoted market prices. The carrying value of the term loan and borrowings under the revolving credit facility approximate their fair value because the interest rates are variable. The fair value of capital lease obligations is based on recent lease rates adjusted for a risk premium.

Assets Measured at Fair Value on a Nonrecurring Basis

The Company's non-financial assets, including property and equipment, goodwill and other intangible assets are measured at fair value on a non-recurring basis and are subject to fair value adjustment in certain circumstances. No impairment of any of these assets was recognized during the nine months ended September 30, 2013 and 2012.
