	March 31, 2023				December 31, 2022
	Gross Unrealized Losses		Fair Value		Gross Unrealized Losses		Fair Value
U.S. treasury securities	$	(1,392)	$	174,013	$	(2,598)	$	158,888

As of March 31, 2023, the total amortized cost basis of the Company’s available-for-sale securities exceeded its fair value by $2.0 million, which was primarily attributable to widening credit spreads and rising interest rates since purchase. The Company reviewed its available-for-sale securities and concluded that the decline in fair value was not related to credit losses and that it is more likely than not that the entire amortized cost of each security will be recoverable before the Company is required to sell them or when the security matures. Accordingly, during the three months ended March 31, 2023, no allowance for credit losses was recorded and instead the unrealized losses are reported as a component of accumulated other comprehensive income (loss).
