Note 4. Net Loss Per Share

Our basic net loss per share attributable to Progenics amounts have been computed by dividing net loss attributable to Progenics by the weighted-average number of common shares outstanding during the period. For all periods presented, the diluted net loss per share is the same as basic net loss per share as the inclusion of other shares of stock issuable pursuant to stock options and contingent consideration would be anti-dilutive.

The following table summarizes anti-dilutive common shares that were excluded from the calculation of diluted loss per share (in thousands):

	March 31,
	2016		2015
Stock options		5,411		6,259
Contingent consideration liability		4,267		2,781
Total anti-dilutive securities		9,678		9,040
