​ (1) The dollar amounts reported are the amounts of total compensation reported for Steven A. Shallcross (our Chief Executive Officer and principal executive officer, or PEO) for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to “Executive Compensation — Summary Compensation Table.” ​ (2) The dollar amounts reported in column (c) represent the amount of “compensation actually paid” to Mr. Shallcross, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Shallcross during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments below were made to Mr. Shallcross’ total compensation for each year to determine the compensation actually paid. ​ (3) The dollar amounts reported represent the average of the amounts reported for the non-PEOs as a group (excluding our PEO) in the “Total” column of the Summary Compensation Table in each applicable year. Frank Tufaro was our only non-PEO (excluding our PEO) included for purposes of calculating the average amounts in 2023 and 2022. For the year 2024, we did not have any named executive officers other than our PEO. ​ (4) The dollar amounts reported represent the average amount of “compensation actually paid” to the NEOs as a group (excluding our PEO), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding our PEO) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments below were made to average total compensation for the NEOs as a group (excluding our PEO) for each year to determine the compensation actually paid, using the same methodology described above in Note (2). ​ (5) Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. ​ The amounts deducted or added in calculating the equity award adjustments with regard to our PEO are as follows:
