The following table sets forth the computation of basic and diluted earnings (loss) from continuing operations per common share (in thousands, except per share amounts):



	Three Months Ended December 31,
	2019		2018
Numerator:
Numerator for basic and diluted earnings (loss) per common share—Net income (loss) attributable to Evoqua Water Technologies Corp.	$	53,145	$	(16,730	)

Denominator for basic net income (loss) per common share—weighted average shares	115,465		113,950
Effect of dilutive securities:

Denominator for diluted net income (loss) per common share—adjusted weighted average shares	120,908		113,950
Basic earnings (loss) attributable to Evoqua Water Technologies Corp. per common share	$	0.46	$	(0.15	)
Diluted earnings (loss) attributable to Evoqua Water Technologies Corp. per common share	$	0.44	$	(0.15	)

Since the Company was in a net loss position for the three months ended December 31, 2018, there was no difference between the number of shares used to calculate basic and diluted loss per share. Because of their anti-dilutive effect, 4,168 common share equivalents, comprised of employee stock options, have been excluded from the diluted EPS calculation for the three months ended December 31, 2018.
