The 2018 Employee Stock Purchase Plan provides eligible employees of the Company and its subsidiaries with the opportunity to purchase shares of the Company’s Class A Common Stock at a purchase price equal to 85% of the Class A Common Stock’s fair market value on the first trading day or last trading day of each purchase period, whichever is lower. The 2018 ESPP generally provides for two six-month purchase periods every twelve months: June 1 through November 30 and December 1 through May 31, except that the initial purchase period under the 2018 ESPP had a duration of five months, commencing on January 1, 2018 and ending on May 31, 2018.
