​ The fair value accounting standards define fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is determined based upon assumptions that market participants would use in pricing an asset or liability. Fair value measurements are rated on a three-tier hierarchy as follows:
| ● | Level 1 inputs: Quoted prices (unadjusted) for identical assets or liabilities in active markets;
| ● | Level 2 inputs: Inputs, other than quoted prices included in Level 1, that are observable either directly or indirectly; and
| ● | Level 3 inputs: Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.
​ There were no transfers between Level 1, 2 or 3 during the six months ended June 30, 2020. The following table presents changes in Level 3 liabilities measured at fair value for the six months ended June 30, 2020: ​
