| Fair Value Measurements |
ASC Topic 820, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 utilizes quoted market prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.
The Company’s cash and restricted cash are measured at fair value and are classified as Level 1 in the fair value hierarchy. The carrying amount of certain of the Company’s financial instruments approximate fair value due to their short maturities. The Company measures derivative liabilities at fair value on a recurring basis and classifies derivative liabilities as Level 3 in the fair value hierarchy.
There were no financial instruments classified as Level 3 in the fair value hierarchy during the year ended December 31, 2017. The following table provides a summary of the changes in fair value of the compound derivative instrument measured at fair value on a recurring basis using significant unobservable inputs during the year ended December 31, 2016.
