Fair Value Disclosures [Abstract]  
Fair Value Information Fair Value Information
The following fair value information is based on a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three levels in the hierarchy used to measure fair value are:
Level 1: Unadjusted quoted prices in active markets accessible at the reporting date for identical assets and liabilities.
Level 2: Quoted prices for similar assets or liabilities in active markets. Quoted prices for identical or similar assets and liabilities in markets that are not considered active or financial instruments for which all significant inputs are observable, either directly or indirectly.
Level 3: Prices or valuations that require inputs that are significant to the valuation and are unobservable.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The following table includes the fair value of our financial instruments for which disclosure of fair value is required (in millions):

Cash equivalents are recorded at cost, which approximates fair value due to their short-term nature. The fair value of amounts borrowed under our Revolving Credit Facility approximates carrying value because borrowings are subject to a variable rate as described in “Debt” in Note 5.
