Earnings per Share | Earnings per Share Basic earnings per share (EPS) is calculated using the weighted-average number of common shares outstanding. Diluted EPS is calculated using the weighted-average number of common shares outstanding, including the dilutive effect of the Company’s: stock option grants; SARs; warrants; ESPP awards; and the 2023 Notes, as determined per the treasury stock method. Effect of Convertible Notes and Related Convertible Note Hedges and Warrants In connection with the issuance of the 2023 Notes, the Company entered into Convertible Note Hedge and Warrant Transactions as described further in Note 9, Convertible Senior Notes Due 2023. The expected collective impact of the Convertible Note Hedge and Warrant Transactions is to reduce the potential dilution that may occur between the conversion price of $59.33 per share and the strike price of the warrants of $80.9063 per share. The 2023 Notes and related Convertible Note Hedge and Warrant Transactions are excluded in the calculation of diluted EPS because their inclusion would be anti-dilutive. Specifically, the denominator of the diluted EPS calculation excludes the additional shares related to the 2023 Notes and warrants, because the average price of the Company's common stock was less than the conversion price of the 2023 Notes of $59.33 per share and the strike price of the warrants of $80.9063 per share. Prior to actual conversion, the Convertible Note Hedge Transactions are not considered in calculating diluted earnings per share, as their impact would be anti-dilutive. In addition to the above described effect of the 2023 Notes and the related Convertible Note Hedge and Warrant Transactions, the Company also excluded the common stock equivalents for outstanding stock-based awards in the calculation of diluted EPS, because their inclusion would be anti-dilutive.
The following table sets forth the computation of basic and diluted net earnings per share for the years ended December 31, 2019, 2018 and 2017:
