Basic earnings per share for the Company’s common stock is computed by dividing, net income (loss) available to common shareholders attributable to common stock for the period by the weighted average number of common shares outstanding during the period.

On June 30, 2014, the Company issued $330 million of 2.25% Convertible Senior Notes due 2019 and on August 24, 2018 and August 31, 2018 the Company issued an aggregate principal amount of $880 million of 2.00% Convertible Senior Notes due 2028 (see Note 9 to these interim condensed consolidated financial statements). Additionally, on March 29, 2019 the Company issued Preferred Stock (see Note 2 and Note 10 to these interim condensed consolidated financial statements). The conversion of these notes and the Preferred Stock are included in the calculation for diluted earnings per share utilizing the “if converted” method. Accordingly, conversion of these Notes and the redeemable convertible preferred stock are not assumed for purposes of computing diluted earnings per share if the effect is antidilutive.

The denominator for diluted net income (loss) per share for the six and three-month periods ended June 30, 2019 and 2018 does not include any effect from the 2019 Notes Capped Call Transactions (as defined in Note 9) or the 2028 Notes Capped Call Transactions (as defined in Note 9) because it would be antidilutive. In the event of conversion of any or all of the 2019 Notes or the 2028 Notes, the shares that would be delivered to the Company under the Capped Call Transactions (as defined in Note 9) are designed to partially neutralize the dilutive effect of the shares that the Company would issue under the Notes. See Note 9 to these interim condensed consolidated financial statements and Note 17 of the financial statements as of December 31, 2018 on Form 10-K for more details. For the six and three-month periods ended June 30, 2019, the effects of the conversion of the redeemable convertible preferred stock would have been antidilutive and, as a consequence, they were not factored into the calculation of diluted earnings per share.

Net income (loss) per share of common stock is as follows for the six and three-month periods ended June 30, 2019 and 2018:
