Financial Instruments and Fair Value Measurements Financial Instruments and Fair Value Measurements
The Company records long-term debt at carrying value less unamortized discount and unamortized fees as it is not required to be carried at fair value on a recurring basis. The fair value of long-term debt was determined using observable inputs (Level 2). The valuation considers the present value of expected future repayments, discounted using a market interest rate equal to the interest margin on the borrowings and variable interest rate.

The following table presents the carrying values and the estimated fair values of long-term debt as of December 31, 2021 and 2020:

(1) At December 31, 2021 and 2020, the carrying value of long-term debt is net of unamortized original issue discount and debt issuance costs of $3.4 million and $5.5 million, respectively.

The Company’s financial instruments, including cash and cash equivalents, deposits, accounts receivable, and accounts payable are carried at cost, which approximates their fair value due to the short-term nature of these instruments. The Company does not have financial instruments that are measured at fair value on a recurring basis as of December 31, 2021 and 2020.
