(Loss) Earnings per diluted share is computed by giving effect to all potentially dilutive stock awards that are outstanding. The computation of (Loss) Earnings per diluted share excludes the effect of the potential exercise of stock-based awards, when the effect of the potential exercise would be anti-dilutive. PSUs vest based upon achievement of performance targets and are excluded from the diluted shares outstanding unless the performance targets have been met as of the end of the applicable reporting period regardless of whether such performance targets are probable of achievement.
