Basic earnings (loss) per share attributable to common stockholders is computed by dividing net income (loss) by the weighted average common shares outstanding during the period. Diluted earnings (loss) per share attributable to common stockholders is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include the assumed exercise of employee stock options, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units, including market-based performance units based on the expected achievement of performance targets. In computing diluted earnings (loss) per share attributable to common stockholders, we utilize the treasury stock method.
