The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value.
Level 1 ‑ inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2 ‑ inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data or other means; and
Level 3 ‑ inputs are unobservable (supported by little or no market activity).
The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs.
The following table presents the fair value of Company's assets that are measured at fair value on a recurring basis for the periods presented:
