As of June 30, 2023, no allowance for expected credit losses has been recognized in relation to securities in an unrealized loss position. This is because the impairments are not severe, do not represent a significant proportion of the total fair market value of the investments and all securities have an investment-grade credit rating. Furthermore, the Company does not intend to sell the debt securities in an unrealized loss position, believes that it has the ability to hold the debt securities to maturity, and it is currently unlikely that the Company will be required to sell these securities before the recovery of the amortized cost.
