Fair Value Measurement

Note 7. Fair Value Measurement

Certain assets and liabilities are required to be recorded at fair value on a recurring basis. See Note 13, Derivatives, for further discussion on financial assets and liabilities that are carried at fair value on a recurring basis in the Consolidated Balance Sheets.

In addition to assets and liabilities that are recorded at fair value on a recurring basis, we are required to record certain assets and liabilities at fair value on a nonrecurring basis, generally as a result of acquisitions or the re-measurement of assets resulting in impairment charges.

The fair value as of the measurement date, net book value as of the end of the year and related impairment charge for assets measured at fair value on a nonrecurring basis subsequent to initial recognition during the years ended December 31, 2020, 2019 and 2018 were as follows:

	Year Ended December 31, 2020				As of December 31, 2020
	Impairment Charge		Fair Value Measurement (Level 3)		Net Book Value
Long-lived assets	$	4.5	$	—	$	—
Other intangible assets		0.7		—		—
Total	$	5.2	$	—	$	—

	Year Ended December 31, 2019				As of December 31, 2019
	Impairment Charge		Fair Value Measurement (Level 3)		Net Book Value
Long-lived assets	$	0.6	$	—	$	—
Other intangible assets		0.2		—		—
Total	$	0.8	$	—	$	—

	Year Ended December 31, 2018				As of December 31, 2018
	Impairment Charge		Fair Value Measurement (Level 3)		Net Book Value
Long-lived assets	$	13.7	$	—	$	—
Other intangible assets		0.2		—		—
Total	$	13.9	$	—	$	—

Our accounting and finance management determines the valuation policies and procedures for Level 3 fair value measurements and is responsible for the development and determination of unobservable inputs. In 2020 the Fair Value of long-lived assets which were ultimately impaired was determined to be $0. These assets were therefore written off and have no remaining Net Book Value.
