For the three and six months ended June 30, 2021, approximately 34,000 and 61,000 shares, respectively, 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 and six months ended June 30, 2020.
