Fair Value Measurements |
Fair value of financial instruments | ​ The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company uses the income and market approaches to determine the fair value of its assets and liabilities. The three levels of the fair value hierarchy are set forth below:
| ● | Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
| ● | Level 2 – Inputs other than quoted prices in active markets included within Level 1 that are observable for the asset or liability, either directly or indirectly.
| ● | Level 3 – Unobservable inputs for the asset or liability.
