Since their inclusion in the calculation of diluted earnings per share would have been anti-dilutive, options to purchase 0.3 million shares of Class A Common Stock have been excluded for the nine months ended January 31, 2018 and 2017, respectively. There were no options excluded for the three months ended January 31, 2018 and 0.3 million options were excluded for the three months ended January 31, 2017. In addition, for the nine months ended January 31, 2018 and 2017, less than 0.1 million unvested restricted shares have been excluded as their inclusion would have been antidilutive, respectively. There were no unvested restricted shares excluded for the three months ended January 31, 2018 and 0.1 million unvested restricted shares were excluded for the three months ended January 31, 2017. During the three months ended January 31, 2018, the Company did not repurchase any shares of common stock. During the three months ended January 31, 2017, the Company repurchased 0.3 million shares of common stock at an average price of $55.14.
