Weighted-average number of common shares outstanding and loss per share available to IPG common stockholders were equal on a basic and diluted basis for the three and six months ended June 30, 2020, respectively, because our potentially dilutive securities are anti-dilutive as a result of the net loss available to IPG common stockholders. The potential dilutive effect of stock options and restricted shares on basic weighted-average number of common shares outstanding totaling 2.9 and 3.3 were excluded from the diluted loss per share calculation for the three and six months ended June 30, 2020, respectively.
