Accounting guidance establishes a framework for measuring the fair value of financial instruments, providing a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities, or “Level 1” measurements, followed by quoted prices of similar assets or observable market data considering the assets' underlying maturities, or “Level 2” measurements, and the lowest priority to unobservable inputs, or “Level 3” measurements.
The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used should seek to maximize the use of observable inputs and minimize the use of unobservable inputs.
Cash and cash equivalents, borrowings under the revolving credit facilities and long-term debt are the only items measured at fair value on a recurring basis.
We do not have any financial assets measured at fair value on a nonrecurring basis. Nonfinancial assets measured at fair value on a nonrecurring basis include items such as long-lived assets held and used that are measured at fair value resulting from impairment, if deemed necessary.
