1. | In all the years in question, Mitchell J. Krebs was our Chief Executive Officer.
2. | For performance-based awards, the fair value of equity awards in the “Compensation Actually Paid” or “CAP” columns is calculated using a Monte Carlo simulation valuation model as of the applicable year-end date(s), and in all cases based on volatility and risk free rates determined as of the revaluation date based on the expected life period and an expected dividend rate of 0% and takes into consideration the probability of achievement as of each such date.
| For the portion of CAP that is based on year-end stock prices, the following prices were used: 2022 $3.36, 2021 $5.04 and 2020 $10.35.
| The following tables set forth the adjustments made during each year represented in the pay versus performance (“PVP”) table to arrive at CAP to our NEOs during each of the years in question:
