Financial Instruments

Marketable securities classified as available-for-sale on March 31, 2022 and December 31, 2021, consisted of the following (in thousands):

			March 31, 2022
			Maturity			Amortized Cost			Unrealized Gains			Unrealized Losses			Fair Value
U.S. Treasury bills			Less than one year			$	318,419		$	—		$	(373)		$	318,047

			December 31, 2021
			Maturity			Amortized Cost			Unrealized Gains			Unrealized Losses			Fair Value
U.S. Treasury bills			Less than one year			$	416,559		$	—		$	(50)		$	416,509

As of March 31, 2022 and December 31, 2021, all marketable securities had contractual maturities less than one year. Marketable securities with maturities greater than one year are classified as current because management considers all marketable securities to be available for current operations. The Company does not intend to sell its marketable securities and it is not likely that the Company will be required to sell these securities before recovery of their amortized cost bases.
