Stock-Based Compensation [Abstract]  
Restricted Stock Units
During the years ended December 31, 2023 and 2022, we issued RSUs and PRSUs to employees which vest upon the achievement of specific market-based or time-based measures. The fair value of RSU’s is calculated using the stock price on the grant date and expensed ratably over the service period. The fair value for PRSU’s is determined using a Monte Carlo simulation model and expensed ratably over the derived service period, which typically ranges between one year and five years.

The following table summarizes the information about vested and unvested restricted stock units for the years ended December 31, 2023 and 2022.
