Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are listed below.

Level 1 — This level is defined as quoted prices in active markets for identical assets or liabilities. Our cash equivalents and restricted cash are instruments of the U.S. Treasury or highly-rated money market mutual funds. The assets measured as Level 1 in the fair value hierarchy are summarized below:



	Level 1
	December 31, 2019		December 31, 2018
	(in millions)
Assets:
Cash equivalents	$	57.9	$	124.9
Restricted cash	111.4		171.6
Total assets	$	169.3	$	296.5

Level 2 — This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Interest rate hedges are valued at exit prices obtained from each counterparty. Foreign currency hedges are valued at exit prices obtained from each counterparty, which are based on currency spot and forward rates and forward points. The liabilities measured as Level 2 in the fair value hierarchy are summarized below:



	Level 2
	December 31, 2019		December 31, 2018
	(in millions)
Assets:
Foreign currency hedge ⁽¹⁾	$	1.2	$	—
Total assets	$	1.2	$	—

Liabilities:
Interest rate hedge ⁽²⁾	$	28.0	$	12.9
Total liabilities	$	28.0	$	12.9

⁽¹⁾Included in other assets in our Consolidated Balance Sheets.

⁽²⁾ Included in accrued liabilities in our Consolidated Balance Sheets.

Level 3 — This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As of December 31, 2019 and 2018, we have no assets measured as Level 3 in the fair value hierarchy, except as described in Note 10 and Note 11.

See Note 8 for the estimated fair values of our debt instruments. The fair values of all other financial instruments are estimated to approximate carrying value.
