From the total of $265 and $2,885 unrealized losses as of December 31, 2024 and 2023, $250 and $2,477 were in continuous unrealized loss for more than 12 months, respectively. The unrealized losses are mainly driven by the higher interest rate environment and the recent interest rate hikes by global central banks during 2023-2024, which was due mainly to elevated inflation rates, therefore negatively impacted the fair value of securities in the Company’s portfolio.

As of December 31, 2024 and 2023, interest receivable amounted to $3,492 and $3,354, respectively, and is included within other receivables in the balance sheet.
