8. 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,
	2023		2022		Input Level
Trading investments	$	31.6	$	25.1		1

The fair value of trading investments has been measured using the market approach (Level 1) and reflect quoted market prices. Trading investments are classified in other assets in our Consolidated Balance Sheets.

Financial Instruments

The carrying amount of our senior credit facility and senior notes not measured at fair value on a recurring basis was $1.58 billion and $1.26 billion at December 31, 2023 and 2022, 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 $1.57 billion and $1.24 billion at December 31, 2023 and 2022, respectively.

The carrying amounts of all other instruments at December 31, 2023 and 2022, approximate their fair value due to the short maturity of these instruments.
