Fair Value Measurements

Note 3 - Fair Value Measurements

 

The carrying amounts of our short term financial instruments, which primarily include cash and cash equivalents, accounts receivable (billed and unbilled), and accounts payable approximate their fair values due to their short term maturities. We define fair value 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 at the measurement date. We report assets and liabilities that are measured at fair value using a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs.  The three levels of inputs used to measure fair value are as follows:


 

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

 

  Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

 

  Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.  This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

 

An asset's or liability's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.  At each reporting period, we perform a detailed analysis of our assets and liabilities that are measured at fair value. All assets and liabilities for which the fair value measurement is based on significant unobservable inputs or instruments which trade infrequently and therefore have little or no price transparency are classified as Level 3.

 

We have segregated our financial assets and liabilities that are measured at fair value into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below. We have no non-financial assets and liabilities that are measured at fair value on a recurring basis.


The following table represents the Company's fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis:

The following table sets forth a summary of changes in the fair value of the Company's Level 3 liabilities for the three months ended March 31, 2015 and 2014:

 

Balance as of   Unrealized     Balance as of  
December 31,   (Gains)     March 31,  
Description 2014   2015     2015  
Derivative liabilities related to stock purchase warrants $ 807,679     $ (338,245 )   $ 469,434  

 

Balance as of   Unrealized     Balance as of  
December 31,   (Gains)     March 31,  
Description 2013   2014     2014  
Derivative liabilities related to stock purchase warrants $ 1,740,235     $ (242,641 )   $ 1,497,594  


At March 31, 2015 and 2014, derivative liabilities are comprised of warrants to purchase 1,775,419 and 2,899,991 shares of common stock, respectively. The warrants are considered to be derivative liabilities due to the presence of net settlement features and/or non-standard anti-dilution provisions, and as a result, are recorded at fair value at each balance sheet date, with changes in fair value recorded in the accompanying unaudited condensed consolidated statements of operations. The fair value of our warrants is determined based on the Black-Scholes option pricing model. Use of the Black-Scholes option pricing model requires the use of unobservable inputs such as the expected term, anticipated volatility and expected dividends. Changes in any of the assumptions related to the unobservable inputs identified above may change the stock purchase warrants' fair value; increases in expected term, anticipated volatility and expected dividends generally result in increases in fair value, while decreases in the unobservable inputs generally result in decreases in fair value. Unrealized gains and losses on the fair value adjustments for these derivative instruments are classified in other income (expense) as the change in fair value of derivative instruments in the accompanying unaudited condensed consolidated statements of operations.

Assets Measured at Fair Value on a Nonrecurring Basis

 

The Company measures its long-lived assets, including, property and equipment and goodwill, at fair value on a nonrecurring basis. These assets are recognized at fair value when they are deemed to be other-than-temporarily impaired. (See Note 2- Summary of Significant Accounting Policies). As of March 31, 2015, the Company had no other assets or liabilities that were measured at fair value on a nonrecurring basis.
