Schedule of Changes in Fair Value Liabilities

The following table presents changes in Level 3 liabilities measured at fair value for the years ended December 31, 2018 and 2017.

Unrealized gains and losses associated with liabilities within the Level 3 category include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long- dated volatilities) inputs.
