The following average number of stock options were antidilutive, and therefore, were not included in the diluted earnings per share calculations: 

	Three Months Ended		Six Months Ended

Average number of stock options	—	12,750,000	5,192,000	11,737,000

The change in the average number of stock options that were antidilutive in the three and six months ended June 30, 2013 compared to the same period last year was primarily due to changes in the company’s average stock price.
