Tabular List [Table Text Block]

The table above shows the relationships between the executive compensation actually paid to the PEOs and our other non-PEO NEOs and our TSR, in general declining as the TSR declined, with exceptions largely reflecting lump sum severance payments, among other items. In line with our Compensation Peer Group TSR, our TSR has declined over the last three years, reflecting the market’s reaction to the end of FDA enforcement discretion, resulting in our inability to sell certain of our products in the United States, and our unsuccessful Phase 2b KOA clinical trial, as well as poor market conditions for our peers generally. The Company also sets compensation goals and measures performance to determine compensation looking at TSR and three other primary measures:

Net Sales – Our net sales (the financial measure we believe has been most important to our compensation determinations for all our NEOs in 2022) have increased over the three-year period, but not at the target levels we have set for ourselves, and this is reflected in the lower executive compensation actually paid over the same three-year period.

Adjusted EBITDA – Our Adjusted EBITDA has declined over the three-year period, which was expected due, in part, to the end of enforcement discretion as mentioned above, along with other expenses associated with items that we do not expect to recur in the future.

R&D Goals – The Company also set several R&D goals for the business in order to continue to bring new products to the market. In late-2022, we were able to successfully launch two such products for our Wound & Surgical business and continue to invest in R&D activities with the aim of continuing to launch additional products in future periods.

Our net loss variations over the three year period have been more reflections of the end of FDA enforcement discretion and other factors, and have therefore had less impact on our executive compensation actually paid.
