Fair Value Disclosures [Abstract]

Schedule of Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities, which generally are not applicable to non‑financial assets and liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as definitive sales agreements, appraisals or established market values of comparable assets. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability and include situations where there is little, if any, market activity for the asset or liability, such as internal estimates of future cash flows.

Our non‑financial assets and liabilities not permitted or required to be measured at fair value on a recurring basis typically relate to long‑lived assets held and used, long‑lived assets held for sale and goodwill. The following table presents this information about assets measured at fair value at December 31, 2020 and indicates the fair value hierarchy of the valuation techniques we utilized to determine such fair values:

	December 31, 2020		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Long-lived assets held for sale	$	140	$	—	$	140	$	—
Long-lived assets held and used	483		—		483		—
