Note 10.  Fair Value of Financial Instruments​

The carrying value amounts of cash and cash equivalents, restricted cash, accounts receivable, prepaid expenses, notes receivable and other current assets, accounts payable, accrued expenses, bank acceptance payable and other current liabilities approximate fair value because of the short-term maturity of these instruments. The Company believes that the interest rates in effect at each period end represent the current market rates for similar borrowings. 

The fair value of convertible senior notes is measured for disclosure purposes only. The fair value and carrying amount of our convertible senior notes as of  June 30, 2024 was $70.3 million and $76.7 million, respectively. As of December 31, 2023, the fair value and carrying amount of our convertible senior notes were both $76.5 million. The fair value is based on observable market prices for this debt, which is traded in less active markets and are therefore classified as a Level 2 fair value measurement.
