Net Income per Share
Net Income per Share
Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by using the weighted average number of common shares outstanding, including potential dilutive shares of common stock assuming the dilutive effect of outstanding stock options and restricted stock using the treasury stock method. Weighted average shares from common share equivalents in the amount of 36,028 and 51,156 for the three months ended and 245,009 and 358,992 for the nine months ended September 30, 2017 and 2016, respectively, were excluded from the dilutive shares outstanding because their effect was anti-dilutive.
For purposes of considering the Convertible Notes in determining diluted net income per share, it is the current intent of the Company to settle conversions of the Convertible Notes through combination settlement, which involves repayment of the principal portion in cash and any excess of the conversion value over the principal amount (the “conversion premium”) in shares of our common stock. Therefore, only the impact of the conversion premium will be included in total dilutive weighted average shares outstanding using the treasury stock method. No conversion premium existed as of September 30, 2017, and as such, there was no dilutive impact from the Convertible Notes for the three and nine month periods ended September 30, 2017. The Warrants sold in connection with the issuance of the Convertible Notes will not be considered in calculating the total dilutive weighted average shares outstanding until the price of the Company’s common stock exceeds the strike price of $57.58 per share, as described in Note 6. When the price of the Company’s common stock exceeds the strike price of the Warrants, the effect of the additional shares that may be issued upon exercise of the Warrants will be included in total dilutive weighted average shares outstanding using the treasury stock method. The Note Hedges purchased in connection with the issuance of the Convertible Notes are considered to be anti-dilutive and therefore do not impact the Company’s calculation of diluted net income per share. Refer to Note 6 for further discussion regarding the Convertible Notes.
As required by ASU 2016-09, the weighted average effect of dilutive securities for the three and nine month periods ended September 30, 2017, was calculated without including consideration of windfall tax benefits, resulting in the repurchase of fewer hypothetical shares and a greater dilutive effect. This change was applied on a prospective basis, and dilutive securities for the same period in 2016 have not been adjusted.
