The Company computed basic net income per common share from continuing operations attributable to its stockholders using net income from continuing operations available to common stockholders and the weighted average number of common shares outstanding during the period. The Company computed diluted net income per common share from continuing operations attributable to its stockholders using net income from continuing operations available to common stockholders and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs. Weighted average common shares exclude the effect of option shares which are not dilutive. There were no anti-dilutive option shares for the years ended March 31, 2018 and March 31, 2017. For the year ended March 31, 2016, the number of option shares that were antidilutive was 0.3 million.

Diluted net income per common share from continuing operations attributable to stockholders for fiscal 2018, 2017, and 2016 includes 1.3 million, 12.7 million and 10.7 million shares, respectively, issuable upon the exchange of the Company's 2007 Junior Debt. The Company's 2007 Junior Debt was fully settled as of December 31, 2017 (see Note 11 for details on the settlement of convertible debt), with the Company issuing an aggregate of 3.7 million shares in the settlement of $143.8 million principal amount in fiscal 2018 and an aggregate of 12.0 million shares in the settlement of $431.3 million principal amount in fiscal 2017. The shares that were issued are included in the weighted average dilutive common shares outstanding through the date of the issuance and were reflected in the weighted average common shares outstanding thereafter. Diluted net income per common share from continuing operations attributable to stockholders for fiscal 2018 and 2017 includes 10.3 million shares and 0.5 million shares, respectively, issuable upon the exchange of the Company's 2015 Senior Debt. The convertible debt has no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion. Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method. The following is the weighted average conversion price per share used in calculating the dilutive effect (See Note 11 for details on the convertible debt):
