LOSS PER SHARE

Basic loss per share is determined by dividing net loss attributable to Key by the weighted average number of common shares actually outstanding during the period. Diluted loss per common share is based on the increased number of shares that would be outstanding assuming conversion of potentially dilutive outstanding securities using the treasury stock and “as if converted” methods.

The components of our loss per share are as follows (in thousands, except per share amounts):

Numerator
Net loss	$	(23,441	)	$	(24,963	)
Denominator
Weighted average shares outstanding	20,369			20,218
Basic and diluted loss per share	$	(1.15	)	$	(1.23	)

Restricted stock units (“RSUs”), stock options, and warrants are included in the computation of diluted earnings per share using the treasury stock method. Restricted stock awards are legally considered issued and outstanding when granted and are included in basic weighted average shares outstanding.

The company has issued potentially dilutive instruments such as RSUs, stock options, and warrants. However, the company did not include these instruments in its calculation of diluted loss per share during the periods presented, because to include them would be anti-dilutive. The following table shows potentially dilutive instruments (in thousands):




	Three Months Ended
	March 31,
	2019	2018
RSUs	1,882	1,166
Stock options	74	163
Warrants	1,838	1,838
Total	3,794	3,167

No events occurred after March 31, 2019 that would materially affect the number of weighted average shares outstanding.
