Note 4 – Fair Value Measurements

Liabilities measured and recorded at fair value on a recurring basis consisted of the following at December 31, 2021 and December 31, 2020:

Schedule of Fair Value of Financial Assets and Liabilities 

Financial instruments with carrying values approximating fair value include cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses, and certain other current liabilities, due to their short-term nature.

In estimating the fair value of the Company’s contingent royalty obligation (see Note 9), the Company used the discounted cash flow method as of December 31, 2021 and 2020. Based on the fair value hierarchy, the Company classified contingent royalty obligation within Level 3 because the valuation inputs are based on projected revenues discounted to a present value.

Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3), which solely consisted of a contingent royalty obligation, during the year ended December 31, 2021 was as follows:

Schedule of Estimated Fair Value of Level 3 Contingent Royalty Obligation 

The contingent royalty obligation is re-measured at each balance sheet date using several assumptions, including the following: 1) estimated sales growth, 2) length of product cycle, 3) patent life, 4) discount rate (21% as of December 31, 2021 and December 31, 2020), and 5) rate of royalty payment (3% as of December 31, 2021 and December 31, 2020).

In accordance with ASC-820-10-50-2(g), the Company performed sensitivity analyses of the liability, which was classified as a Level 3 financial instrument. The contingent royalty obligation estimate may be significantly impacted by changes in assumptions used in these analyses. For example, the Company recalculated the fair value of the liability by applying a +/- 2% change to the input variable in the discounted cash flow model; the discount rate. A 2% decrease in the discount rate would increase the liability by approximately $150 and a 2% increase in the discount rate would decrease the liability by approximately $136.
