For the three months ended March 31, 2021, approximately 88,000 shares issuable under equity-based awards were excluded from the calculation of diluted earnings per share as they were anti-dilutive based on the average stock price during the period. There were no anti-dilutive equity-based awards for three months ended March 31, 2020.
