Basic net (loss) income per share is computed by dividing net (loss) income available to common stockholders by the weighted-average number of outstanding common shares during the period. Diluted net income per share reflects the potential dilution that could occur under the more dilutive of either the treasury stock method or the two-class method for calculating the weighted-average number of outstanding common shares. Under the treasury stock method, potential shares of common shares outstanding are not included in the computation of diluted net (loss) income per share if their effect is anti-dilutive.

The following table sets forth the computation of basic and diluted net (loss) income per common share (in millions, except for share and per-share data):
