The Company considers whether unrealized losses have resulted from a credit loss or other factors. The unrealized losses on the Company’s short-term investments as of December 31, 2024, were caused by fluctuations in market value and interest rates as a result of the economic environment and not credit risk. The Company concluded that an allowance for credit losses was unnecessary as of December 31, 2024. It is neither management’s intention to sell nor is it more likely than not that the Company will be required to sell these investments prior to recovery of their cost basis or recovery of fair value. Unrealized gains and losses are included in accumulated other comprehensive loss.

Accrued interest receivable is written off through net realized investment gains (losses) at the time the issuer of the bond defaults or is expected to default on payment. Accrued interest receivable related to short-term investments was $0.5 million and $0.6 million as of December 31, 2024 and December 31, 2023, respectively.
