Basic earnings per share of Class A and Class C common stock is computed by dividing net income attributable to ZoomInfo Technologies, Inc. by the weighted-average number of shares of Class A and Class C common stock outstanding during the period. Diluted earnings per share of Class A and Class C common stock is computed by dividing net income attributable to ZoomInfo Technologies, Inc., adjusted for the assumed exchange of all potentially dilutive instruments for Class A common stock, by the weighted-average number of shares of Class A and Class C common stock outstanding, adjusted to give effect to potentially dilutive elements.

Prior to the IPO, the ZoomInfo OpCo membership structure included Series A Preferred Units, Preferred units, Common units, and Profits Interests in the form of Class P Units. The Company analyzed the calculation of earnings per unit for periods prior to the IPO and determined that it resulted in values that would not be meaningful to the users of these unaudited consolidated financial statements. Therefore, earnings per share information has not been presented for the three and six months ended June 30, 2019.
