The following table presents the calculation of loss per share for the years ended December 31, 2016 and 2015:

In thousands, except per share data	2016		2015
Numerator:
Net loss, as reported	$	(611)	$	(1,749)
Dividends paid on preferred shares		(177)		-
Change in dividends accumulated on preferred shares		(21)		(23)
Net loss attributable to common shares	$	(809)	$	(1,772)
Denominator:
Weighted average shares outstanding		1,711		1,674
Basic and diluted loss per share	$	(0.47)	$	(1.06)

At December 31, 2016 and 2015, dividends accumulated on preferred shares totals $44,000 and $23,000, respectively.

Basic loss per common share is computed by dividing net loss attributable to common shares by the weighted average number of common shares outstanding for the period. Diluted loss per common share is computed by dividing net loss attributable to common shares, by the weighted average number of common shares outstanding, adjusted for shares that would be assumed outstanding after warrants and stock options vested under the treasury stock method.

At December 31, 2016 and 2015, outstanding warrants convertible into 52,000 and 85,300 shares, respectively, of Common Stock were excluded from the calculation of diluted loss per share because their impact would have been anti-dilutive.
