We compute Basic earnings per share by dividing net earnings by the weighted average number of common shares outstanding during the period. Diluted earnings per share gives effect to the potential dilution that could occur if securities or contracts to issue common stock that are dilutive were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. In accordance with ASC 260-10, Earnings Per Share, we calculate the dilutive effect of the 2028 Convertible Notes using the "if-converted" method. As discussed in Note 7 - Senior and Convertible Senior Notes, Net in the consolidated financial statements included in our Annual Report, the Company will settle any convertible note conversions by paying cash up to the principal amount of notes and settle any additional value in cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election. As the Company will settle the principal amount of convertible notes in cash upon conversion, the convertible notes only have a dilutive impact when the average share price of the Company’s common stock exceeds the conversion price, in any applicable period.
