Fair Value of Financial Instruments    

The warrant liability recorded at fair value on the balance sheet as of September 30, 2014 is categorized based upon the level of judgment associated with the inputs used to measure their fair value.  Hierarchical levels, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these liabilities is as follows:
Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date; 
Level 2 - Inputs other than Level 1 inputs that are either directly or indirectly observable; and 
Level 3 - Unobservable inputs, for which little or no market data exist, therefore requiring an entity to develop its own assumptions.
 The following table summarizes the warrant derivative liability measured at fair value on a recurring basis as of the dates presented, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:
