Fair value measurements
Note 6 - Fair value measurements
 
The Company classifies its financial instruments using a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:
 
Level 1 - defined as observable inputs such as quoted prices in active markets;
Level 2 - defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and
Level 3 - defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions such as expected revenue growth and discount factors applied to cash flow projections.
 
Financial assets and liabilities measured at fair value on a recurring basis
The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the hierarchy.
 
Prior to its IPO, certain stock purchase warrants contained cash settlement features and, accordingly, the Company considered them to be derivative financial instruments and accounted for them at fair value using level 3 inputs. As a result of the Company’s IPO and elimination of the cash settlement features pursuant to their terms, those stock purchase warrants were reclassified to equity. For periods prior to the IPO, the Company determined the fair value of these derivative liabilities using a hybrid valuation method that consisted of a probability weighted expected return method that values the Company’s equity securities assuming various possible future economic outcomes while using an option pricing method (that treated all equity linked instruments as call options on the Company’s equity value with exercise prices based on the liquidation preference of the Series A Preferred Stock ) to estimate the allocation of value within one or more of the scenarios. Using this hybrid method, unobservable inputs included the Company’s equity value, the exercise price for each option value, expected timing of possible economic outcomes such as initial public offering, risk free interest rates and stock price volatility. The following tables set forth a summary of changes in the fair value of Level 3 liabilities measured at fair value on a recurring basis for the year ended December 31, 2015:
