Net (loss) Income Attributable to ORBCOMM Inc. Common Stockholders

5. Net (loss) income Attributable to ORBCOMM Inc. Common Stockholders

Basic net (loss) income per common share is calculated by dividing net (loss) income attributable to ORBCOMM Inc. by the weighted-average number of common shares outstanding for the period. Diluted net loss per common share is the same as basic net loss per common share, because potentially dilutive securities would have an antidilutive effect as the Company incurred a net loss for the three months ended March 31, 2014. For the three months ended March 31, 2013, the Company included the effect of 1,306,344 SARs, RSUs, shares of Series A convertible preferred stock and stock options in its diluted weighted average common shares outstanding.

The potentially dilutive securities excluded from the determination of diluted income per share, as their effect is antidilutive, are as follows:

	Three months ended March 31,
	2014		2013
Series A convertible preferred stock		155,335		—
SARs		4,427,818		3,513,241
RSUs		165,255		42,391
Stock options		50,000		424,116
		4,798,408		3,979,748
