3. Fair Value Measurement

Note 3. Fair Value Measurement

The Company's financial assets and liabilities are measured using inputs from the three levels of the fair value hierarchy. The three levels are as follows:

Level 1- Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2- Inputs are other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

Level 3- Inputs are unobservable and reflect the Company's assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available.

Summary of Assets Recorded at Fair Value

In accordance with the fair value hierarchy described above, the following table shows the fair value of the Company's financial assets that are required to be measured at fair value as of June 30, 2015 and December 31, 2014 (in thousands):

      As of June 30, 2015
      Level 1     Level 2     Level 3     Total
Money market fund and trust cash sweep investments (1)   $ 45,208    $ -     $ -     $ 45,208 
     Total assets   $ 45,208    $ -     $ -     $ 45,208 
                         
      As of December 31, 2014
      Level 1     Level 2     Level 3     Total
Money market fund and trust cash sweep investments (1)   $ 26,297    $ -     $ -     $ 26,297 
     Total assets   $ 26,297    $ -     $ -     $ 26,297 

 

(1) The Company's money market and trust cash sweep investments are included in cash and cash equivalents within the Condensed Consolidated Balance Sheet.
   

The Company's cash equivalents are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices or broker or dealer quotations for similar assets. These investments are initially valued at the transaction price and subsequently valued utilizing third-party pricing providers or other market observable data. Data used in the analysis include reportable trades, broker/dealer quotes, bids and offers, benchmark yields and credit spreads. The Company validates the prices provided by its third-party pricing providers by reviewing their pricing methods, analyzing pricing inputs and confirming that the securities have traded in normally functioning markets. The Company did not adjust or override any fair value measurements provided by its pricing providers as of June 30, 2015 or December 31, 2014.

As of June 30, 2015 and December 31, 2014, the Company did not have any investments in Level 3 securities.

There were no transfers of assets or liabilities between Level 1 and Level 2 during the three or six months ended June 30, 2015 and 2014.

The carrying amounts reflected in the condensed consolidated balance sheets for certain short-term financial instruments including accounts receivable, accounts payable, accrued expenses, and other liabilities approximate fair value due to their short-term nature.

Summary of Liabilities Recorded at Carrying Value

The fair and carrying value of our debt instruments are detailed as follows (in thousands):

      As of June 30, 2015     As of December 31, 2014
      Fair     Carrying     Fair     Carrying
      Value     Value     Value     Value
4.25% Convertible Notes   $ 96,736    $ 102,136    $ -     $ -  
Derivative liability     19,777      19,777      -       -  
8.00% Convertible Notes     -       -       129,320      65,000 
Contingent consideration     29,327      29,327      -       -  
Treximet Notes     182,332      220,000      167,114      220,000 
     Total   $ 328,172    $ 371,240    $ 296,434    $ 285,000 

 

The fair values of the Company's liabilities were estimated using the following methodologies. Within the hierarchy of fair value measurements, these are Level 3 fair values.

Convertible Notes

The fair values of the Convertible notes were estimated using the (i) terms of the convertible notes; (ii) rights, preferences, privileges, and restrictions of the underlying security; (iii) time until any restriction(s) are released; (iv) fundamental financial and other characteristics of the Company; (v) trading characteristics of the underlying security (exchange, volume, price, and volatility); (vi) valuation of derivative liability; and (vii) precedent sale transactions.

Derivative Liability

The fair value of the derivative liability was determined using a "with and without" scenario. Under this methodology, valuations are performed on the convertible note inclusive of all terms as well as for a convertible note that has identical terms and features but excluding the conversion option. The difference between the two valuations is equal to the fair value of the conversion option.

Contingent Consideration

The fair value of contingent consideration is based on two components- The Regulatory milestone and the Commercial milestone.

For the Regulatory milestone, the expected Regulatory Earn out payment was discounted taking into account (a) the Company's cost of debt, (b) the expected timing of the payment and (c) subordinate nature of the Earn out obligation.

The fair value of the Commercial milestone was determined using a Monte Carlo simulation. This simulation assumed a risk-neutral framework, whereby future net revenue was simulated over the earn out period using Geometric Brownian Motion. For each simulation path, the earn out payments were calculated based on the achievement of the Revenue Milestone and then were discounted to the Valuation Date.

Treximet Notes

The fair values of the Company's Treximet notes were estimated using a discounted cash flow model.
