[1] Diluted earnings (loss) per share considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect.

[2] These outstanding potential shares of common stock relating to stock options, restricted stock units and performance-based restricted stock units were excluded from the calculation of diluted earnings (loss) per share because (i) the effect of including them would have been anti-dilutive; and (ii) the performance metrics have not yet been achieved for the outstanding potential shares relating to performance-based restricted stock units, which are deemed to be contingently issuable.
