Basic and Diluted Net Income (Loss) Per Share

The following table presents the computation of net income (loss) per share (in thousands, except per share amounts):



	Three Months Ended March 31,
	2020			2019
Numerator:
Net income (loss) attributable to common stockholders	$	(15,473	)	$	5,914
Denominator:
Weighted-average shares used to compute net income (loss) per share attributable to common stockholders, basic	65,569			61,926
Effect of dilutive securities:
Convertible senior notes	—			2,002
Contingently issuable shares	—			11
Employee stock awards	—			3,539
Weighted-average shares used to compute net income (loss) per share attributable to common stockholders, diluted	65,569			67,478
Net income (loss) per share attributable to common stockholders, basic	$	(0.24	)	$	0.10
Net income (loss) per share attributable to common stockholders, diluted	$	(0.24	)	$	0.09

The following weighted-average equivalent shares of common stock, excluding the impact of the treasury stock method, were excluded from the diluted net income (loss) per share calculation because their inclusion would have been anti-dilutive (in thousands):

Stock awards	4,146	203
Convertible senior notes	6,137	—
Total shares excluded from net loss per share	10,283	203

It is our current intent to settle the principal amount of each series of the Notes with cash and, therefore, we use the treasury stock method for calculating any potential dilutive effect of the conversion options on diluted net income per share. The conversion options may have a dilutive impact on net income per share of common stock when the average market price per share of our Class A common stock for a given period exceeds the conversion price of the 2023 Notes and 2024 & 2026 Notes of $44.33 and $189.36 per share, respectively.
