18. Fair Values of Financial Instruments

The carrying values of cash and cash equivalents, trade receivables and accounts payable approximate fair value due to the short-term maturity of these items. These fair value estimates are considered Level 1 fair value estimates in the fair value hierarchy of fair value accounting.

The estimated fair value of the Company’s outstanding debt balances as of December 31, 2018 and 2017 is set forth below (in thousands):

	December 31, 2018				December 31, 2017
	Carrying		Fair		Carrying		Fair
	Value		Value		Value		Value
Borrowings under Credit Agreement:
Revolving credit facility	$	—	$	—	$	268,000	$	268,000
3.95% Senior Notes		525,000		482,488		—		—
4.97% Series A Senior Notes		300,000		300,043		300,000		303,966
4.27% Series B Senior Notes		300,000		293,900		300,000		295,616
Total debt	$	1,125,000	$	1,076,431	$	868,000	$	867,582

The carrying value of the balances outstanding under the revolving credit facility approximates its fair values as this instrument has floating interest rates. The fair value of the 3.95% Senior Notes at December 31, 2018 is based on discounted cash flows associated with the notes using the market rate of interest at December 31, 2018 of 5.07%. The fair value estimate of the 3.95% Senior Notes is considered a Level 1 fair value estimate in the fair value hierarchy of fair value accounting. The fair values of the Series A Notes and Series B Notes at December 31, 2018 and 2017 are based on discounted cash flows associated with the respective notes using current market rates of interest at those respective dates. For the Series A Notes, the current market rates used in measuring this fair value were 4.97% at December 31, 2018 and 4.46% at December 31, 2017. For the Series B Notes, the current market rates used in measuring this fair value were 4.92% at December 31, 2018 and 4.64% at December 31, 2017. These fair value estimates are based on observable market inputs and are considered Level 2 fair value estimates in the fair value hierarchy of fair value accounting.
