The calculation of diluted earnings per share does not include anti-dilutive options. These options would not be exercised during the period because their exercise price is higher than the average market price for the period. The inclusion of these options would cause the diluted earnings per share to be overstated. The number of excluded options for the year ended December 31, 2012 was 680,000 (1,019,000 for the year ended December 31, 2011).
