9. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Our assets and liabilities measured at fair value are based on valuation techniques which consider prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. These valuation methods are based on either quoted market prices (Level 1) or inputs, other than quoted prices in active markets, that are observable either directly or indirectly (Level 2). The following are assets and liabilities measured at fair value on a recurring basis (in millions):

	Asset/(Liability) Balance
	December 31,
	2021			2020			Input Level
Trading investments	$	26.0		$	23.1			1
Interest rate swap	$	6.3		$	12.5			2
Senior notes, net of unamortized discount and debt issuance costs	$	(356.0	)	$	(361.3	)		2

The fair value of trading investments has been measured using the market approach (Level 1) and reflect quoted market prices. The fair values of interest rate swap and corresponding senior notes have been measured using the income approach (Level 2), which include relevant interest rate curve inputs. Trading investments are classified in other assets in our Consolidated Balance Sheets. At December 31, 2021, the interest rate swap and senior notes are classified in our Consolidated Balance Sheet in prepaid expenses and other current assets and current portion of long-term debt, respectively. At December 31, 2020, the interest rate swap and senior notes are classified in our Consolidated Balance Sheet in other assets and long-term debt, respectively.

Financial Instruments

The carrying amount of our senior revolving line of credit and remaining senior notes not measured at fair value on a recurring basis was $945.2 million and $944.1 million at December 31, 2021 and 2020, respectively. The estimated fair value of these liabilities using the income approach (Level 2), based on their net present value, discounted at our current borrowing rate, was $1.04 billion and $1.09 billion at December 31, 2021 and 2020, respectively.

The carrying amounts of all other instruments at December 31, 2021 and 2020, approximate their fair value due to the short maturity of these instruments.
