Upon us adopting ASU 2020-06 using the modified retrospective transition method on January 1, 2021, we applied the “if-converted” method for calculating any potential dilutive effect of the conversion of the 2019 Notes or the 2021 Notes on diluted net loss per share for the three months ended March 31, 2022 and March 31, 2021.

The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net loss per share for the periods presented (in thousands, except per share amounts):

	Three Months Ended March 31,
	2022			2021
Numerator:
Net loss	$	(10,461	)	$	(9,416	)
Denominator:
Weighted-average shares outstanding — basic and diluted		24,980			23,671
Net loss per share — basic and diluted	$	(0.42	)	$	(0.40	)

The following table presents the outstanding shares of our common stock equivalents excluded from the computation of diluted net loss per share as of the dates presented because their effect would have been antidilutive (in thousands):

	Three Months Ended March 31,
	2022		2021
Stock options		2,167		2,723
RSUs, MSUs, and PSUs		1,900		779
Employee stock purchase plan shares		27		28
2019 Notes		285		2,496
2021 Notes		2,589		—
