Schedule of Classifications of Fair Value Hierarchy | We classify the inputs used to measure fair value into the following hierarchy:

Level 2 |  | Unadjusted quoted prices in active markets for similar assets or liabilities; unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability.
Level 3 |  | Unobservable inputs for the asset or liability.
