Treasury bill was purchased on October 10, 2023, at a cost of $10,414, and fair value accretes to maturity date at an interest rate of 5.35%. The treasury bill was classified as Level 2 as it is considered “off the run” because similar treasury bills were issued before the most recent issue and were outstanding as of December 31, 2023 and therefore not considered as liquid as other treasury bills with the same maturity date. As of December 31, 2023, the interest income recorded on these bills was $80.
