    Basic earnings per common share are calculated by dividing net income by the weighted average number of common shares outstanding, which includes 130,624, 73,320 and 32,981 shares of participating securities in 2021, 2020 and 2019, respectively. Diluted earnings per share are calculated by dividing net income by the sum of the weighted average number of common shares outstanding plus the additional common shares that would have been outstanding if potentially dilutive securities had been issued.
    The weighted average common shares outstanding for the diluted earnings per share calculation excludes consideration of 1,499,128, 1,667,325 and 1,082,113 equivalent shares in 2021, 2020 and 2019, respectively, as these shares are anti-dilutive.
