Investments with unrealized losses have been in a loss position for less than twelve months, and the unrealized losses were considered to be temporary in nature. Unrealized losses as of June 30, 2022 are attributed to changes in market interest rates. The Company does not intend to sell the investments in an unrealized loss position and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis.

	Amount
Due within one year	$	258,442
Due after one through five years		7,012
