Basic net income (loss) per common share attributable to Optimum Communications stockholders is computed by dividing net income (loss) attributable to Optimum Communications stockholders by the weighted average number of common shares outstanding during the period. Diluted income per common share attributable to Optimum Communications stockholders reflects the dilutive effects of stock options, restricted stock, restricted stock units, and deferred cash-denominated awards. For awards that are performance based, the dilutive effect is reflected upon the achievement of the performance criteria. In periods with reported net losses attributable to Optimum Communications stockholders, share-based awards are anti-dilutive and excluded from the calculation of diluted loss per share.

The following table presents a reconciliation of weighted average shares used in the calculations of the basic and diluted net income per share attributable to Optimum Communications stockholders:
