[1] In connection with the issuance of the 2020 Convertible Notes, the Company entered into convertible note hedge and warrant transactions as described in Note 8, “Borrowings.” The 2020 Convertible Notes have no impact on diluted earnings per share until the average quarterly price of the Company’s common stock exceeds the adjusted conversion price of $15.92 per share. If the common stock price exceeds this adjusted conversion price, prior to conversion, the Company will calculate the effect of the additional shares that may be issued using the treasury stock method. If the average price of the Company’s common stock exceeds $20.63 per share for a quarterly period, the Company’s weighted-average shares used in computing diluted net income per share will be impacted by the effect of the additional potential shares that may be issued related to the warrants using the treasury stock method. The convertible note hedge is not considered for purposes of the diluted earnings per share calculation, as its effect would be antidilutive.

[2] These amounts are excluded from the computation of diluted net income per share.
