Fair Value Measurements
Note 6 — Fair Value Measurements
   
The Company has adopted FASB ASC Topic 820, “Fair Value Measurement and Disclosures”, (“ASC 820”). This topic defines fair value, establishes a framework for measuring fair value under US GAAP and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:
   
Level 1 — Quoted prices in active markets for identical assets or liabilities.
   
Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, 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.
   
Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value
     
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
   
Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable, and certain accrued liabilities. The carrying amounts of our cash and cash equivalents (which are comprised primarily of deposit and overnight sweep accounts), accounts receivable, accounts payable, and certain accrued liabilities approximate fair value due to the short maturity of these instruments.
   
The Company’s liabilities that are measured at fair value on a recurring basis relate to its contingent consideration resulting from the acquisition of Xoft completed on December 30, 2010. The fair value measurements for this liability are valued using Level 3 inputs. The Company recorded a contingent consideration liability of $5.0 million based upon the estimated fair value of the additional earn-out potential for the sellers that is tied to cumulative net revenue of Xoft products from January 1, 2011 through December 31, 2013, payable January, 2014. During the quarter ended March 31, 2011, the Company recorded a measurement period adjustment of $100,000 and reduced the value of the contingent consideration to $4.9 million. The Company determines the fair value of the contingent consideration liability based on a probability-weighted approach derived from earn-out criteria estimates and a probability assessment with respect to the likelihood of achieving the various earnout criteria. Accordingly, the value of contingent consideration is evaluated each quarter. During the quarter ended June 30, 2011, the Company reduced the value of contingent consideration to $3.8 million as a result of lower expectations of Xoft product revenue. In the quarter ended September 30, 2011, the Company evaluated the revenue expectations of Xoft products and determined that the thresholds were unlikely to be met, and therefore reduced the value of contingent consideration to $0.0. The measurement is based upon significant inputs not observable in the market. Subsequent changes in the value of this liability will be recorded in the statement of operations.
   
The following table sets forth Company’s liabilities which are measured at fair value on a recurring basis by level within the fair value hierarchy.

The changes in the fair value of contingent consideration during the period are as follows:
         
Nine months ended September 30,  
Balance as of December 31, 2010
  $ 5,000  
Measurement period adjustment
    (100 )
Mark to market
    (4,900 )
 
     
Balance as of September 30, 2011
  $ 0  
 
     
   
As noted above the Company recorded an additional $3.8 million reduction in the fair value of the contingent consideration as a gain in the statement of operations during the quarter ended September 30, 2011.
   
Items Measured at Fair Value on a Nonrecurring Basis
   
Certain assets, including our goodwill, are measured at fair value on a nonrecurring basis. These assets are recognized at fair value when they are deemed to be impaired. As noted in Note 8 we recorded an estimated impairment charge for goodwill of $26.8 million during the three months ended September 30, 2011. We did not consider any other assets to be impaired during the three and nine months ended September 30, 2011.
