Fair Value Measurements
5. Fair Value Measurements
 
Accounting guidance on fair value measurements and disclosures defines fair value, establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system, and defines required disclosures. It clarifies that fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts business.
 
The Company's balance sheet contains derivative and warrant liabilities that are recorded at fair value on a recurring basis. The three-level valuation hierarchy for disclosure of fair value is as follows:
 
Level 1: uses quoted market prices in active markets for identical assets or liabilities.
 
Level 2: uses observable market-based inputs or unobservable inputs that are corroborated by market data.
 
Level 3: uses unobservable inputs that are not corroborated by market data.
 
The fair value of the Company’s recorded derivative and warrant liabilities is determined based on unobservable inputs that are not corroborated by market data, which require a Level 3 classification. A modified Binomial Lattice option valuation model was used to determine the fair value with similar assumptions to those described under “Stock-Based Compensation”. The Company records derivative and warrant liabilities on the consolidated balance sheets at fair value with changes in fair value recorded in the consolidated statements of operations.
  
The following table presents the balances of liabilities measured at fair value on a recurring basis by level as of September 30, 2013:

In computing the fair value of the derivative and warrant liability at September 30, 2013 for instruments under the Binomial Lattice option-pricing model, management estimated a 50% probability of a down round financing event at a price of $0.036 and a 20% to 80% probability that existing note holders with exchange priviledges would exchange their existing debentures and warrants for new debentures and warrants.
