The amortized cost and fair value amounts include accrued interest receivable of $3.2 million and $2.5 million as of March 31, 2022 and June 30, 2021, respectively.

As of March 31, 2022, the fair value of the Company’s short-term investments that mature within one year and thereafter was $971.6 million and $171.8 million, respectively, or 85% and 15%, respectively, of the Company’s total short-term investments. As of June 30, 2021, the fair value of the Company’s short-term investments that mature within one year and thereafter was $495.8 million and $159.5 million, respectively, or 76% and 24%, respectively, of the Company’s total short-term investments.

As of March 31, 2022, approximately 300 out of approximately 400 investment positions were in an unrealized loss position. The following table presents gross unrealized losses and fair values for those investments that were in an unrealized loss position as of the dates presented (in thousands):


	March 31, 2022
	Fair value		Unrealized losses
Corporate bonds	$	415,637	$	(3,653	)
U.S. treasury securities		372,165		(2,059	)
Asset backed securities		49,177		(226	)
Total	$	836,979	$	(5,938	)


	June 30, 2021
	Fair value		Unrealized losses
Corporate bonds	$	152,485	$	(55	)
U.S. treasury securities		85,466		(5	)
Asset backed securities		8,089		(1	)
Total	$	246,040	$	(61	)

Most of the Company investments with unrealized losses had been in a continuous unrealized loss position for less than 12 months. Investments with unrealized losses that had been in a continuous unrealized loss position for more than 12 months have not been material. The Company does not intend to sell the investments and it is not likely that the Company will be required to sell the investments before recovery of their amortized cost bases, which will be at maturity. Therefore, the Company does not consider those unrealized investment losses as other-than-temporary impairment of the investments. There have been no significant realized gains or losses on the short-term investments during the three and nine months ended March 31, 2022 and 2021.

The Company has not recorded an allowance for credit losses on investments that were in an unrealized loss position as of March 31, 2022 and June 30, 2021 because they were not material.
