8. Earnings Per Share
At December 31, 2012 and 2011, potential dilutive effects of 2.4 million and 2.2 million shares relating to unvested time-based restricted stock units and stock options were excluded from the computation of earnings per share as their effects were anti-dilutive. At December 31, 2012 and 2011, potential dilutive effects of 2.0 million and 1.8 million shares relating to unvested performance-based stock awards were excluded from the computation of diluted earnings per share as the related performance period is not yet complete. The effects of these performance-based shares will be dilutive in the future to the extent various levels of performance criteria are met.
