Under the treasury stock method, the convertible senior notes will have a dilutive impact on earnings per common share if the Company’s average stock price for the period exceeds the conversion price for the convertible senior notes of $96.89 per share. The warrants will have a dilutive impact on earnings per common share if the Company’s average stock price for the period exceeds the warrant strike price of $130.43 per share. As the Company’s average stock price for the three and nine months ended April 29, 2017 was below the conversion price for the convertible senior notes and the strike price for the warrants, the underlying common shares were anti-dilutive as reflected above. See Note 10, Debt, for additional information related to the Company’s convertible senior notes and warrant transactions.

In connection with the offering of the convertible senior notes, the Company entered into convertible note hedge transactions with counterparties for the purpose of reducing the potential dilution to common stockholders from the conversion of the notes and offsetting any potential cash payments in excess of the principal amount of the notes. Prior to conversion, the convertible note hedge is not included for purposes of the calculation of earnings per common share as its effect would be anti-dilutive. Upon conversion, the convertible note hedge is expected to offset the dilutive effect of the convertible senior notes when the average stock price for the period is above $96.89 per share. See Note 10, Debt, for additional information related to the Company’s convertible note hedge.
