pre_text: The following table summarizes the potentially dilutive common shares that were excluded from diluted weighted-average common shares outstanding because including them would have had an anti-dilutive effect (in thousands): Since the Company expects to settle the principal amount of its outstanding convertible senior notes in cash and any excess in cash or shares of the Company’s Class A Common Stock, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread will have a dilutive impact on diluted net income per share of common stock when the average market price of the Company’s Class A Common Stock for a given period exceeds the conversion price of $81.45 per share for the Notes.
