The following table presents basic and diluted net loss per share for the three and six months ended June 30, 2020 and 2019 (in thousands, except share and per share data):

Basic and diluted net loss per share calculation:

Basic and diluted net loss per share	$	(0.42	)	$	(0.03	)	$	(0.49	)	$	(0.21	)

Basic net loss per share is computed by dividing net loss by the weighted-average number of ordinary shares outstanding during the period. Diluted net loss per share reflects the potential dilution that could occur if securities or other contracts to issue ordinary shares were exercised, converted into ordinary shares or resulted in the issuance of ordinary shares that would have shared in the Company’s earnings.

The computation of diluted net loss per share excluded 9.7 million and 12.0 million shares subject to equity awards for the three and six months ended June 30, 2020, respectively, and 12.4 million and 13.1 million shares (based on the if-converted method) related to the Company’s 2.5% Exchangeable Senior Notes due 2022 (the “Exchangeable Senior Notes”) for the three and six months ended June 30, 2020, respectively, because their inclusion would have had an anti-dilutive effect on diluted net loss per share.

The computation of diluted net loss per share excluded 8.8 million shares subject to equity awards for each of the three and six months ended June 30, 2019, because their inclusion would have had an anti-dilutive effect on diluted net loss per share. During the three and six months ended June 30, 2019, the potentially dilutive impact of the Exchangeable Senior Notes was determined using a method similar to the treasury stock method. Under this method, no numerator or denominator adjustments arose from the principal and interest components of the Exchangeable Senior Notes because the Company had the intent, at that time, and ability to settle the Exchangeable Senior Notes’ principal and interest in cash. Instead, the Company was required to increase the diluted net loss per share denominator by the variable number of shares that would be issued upon conversion if it settled the conversion spread obligation with shares. For diluted net loss per share purposes, the conversion spread obligation was calculated based on whether the average market price of the Company’s ordinary shares over the reporting period was in excess of the exchange price of the Exchangeable Senior Notes. There was no calculated spread added to the denominator for the three and six months ended June 30, 2019. Beginning in the fourth quarter of 2019, with the ordinary share price significantly above the $28.66 exchange price, the Company decided that it no longer had the intent to settle the notes for cash and, as a result, began to prospectively apply the if-converted method to the Exchangeable Senior Notes when determining the diluted net loss per share. By August 3, 2020, the Exchangeable Senior Notes were fully extinguished through exchanges for ordinary shares or cash redemption. Refer to Note 13 for further detail.
