The following table summarizes the Company’s incentive stock option activity and related information for the years ended December 31, 2023 and 2022.

 Schedule of Incentive Stock Option Activity

As of December 31, 2023 and 2022, vested outstanding stock options had $295 thousand and $124 thousand intrinsic value as the exercise price is greater than the estimated fair value of the underlying common stock, respectively. As of December 31, 2023, there was no unrecognized share-based compensation related to unvested stock options, excluding options fully contingent upon certain sales-based milestones being achieved within 18 to 36 months of commercial release.

The Company recognizes compensation expense for stock option awards on a straight-line basis over the applicable service period of the award. The service period is generally the vesting period. The following assumptions were used to calculate share-based compensation expense for year ended December 31, 2023 and 2022:

 Schedule of Assumptions used in Share-based Compensation

The Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. Accordingly, the Company has elected to use the “simplified method” to estimate the expected term of its share-based awards. The simplified method computes the expected term as the sum of the award’s vesting term plus the original contractual term divided by two.

Based on the lack of historical data of volatility for the Company’s common stock, the Company based its estimate of expected volatility on a weighted-average of the historical volatility of comparable public companies that manufacture similar products and are similar in size, stage of life cycle, and financial leverage.
