Fair Value Measurements

Note 3. Fair value measurements

There were no financial assets and liabilities outstanding that were remeasured at fair value on a recurring basis as of December 31, 2022 and 2021. The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to their short-term nature.

The fair value of the Notes was determined based on significant inputs not observable in the market, which represents a level 3 measurement within the fair value hierarchy. Prior to the closing of the Rights Offering, the fair value of the Notes was estimated as a combination of the Company’s equity, an option on the Company’s equity valued using the Black-Scholes option pricing model, and a short position in a bond valued under the discounted cash flow model. The conversion date fair value of the Notes was estimated based on the closing price of the Company's common stock adjusted for the impact of certain legal restrictions on the Conversion Shares (see Note 8).

The following table provides a summary of the changes in the estimated fair value of the Notes:
