¹ Dilutive effect of the company's employee compensation plans are excluded from calculation of dilutive loss per share of common stock from continuing operations for the three months ended September 30, 2012.

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

	Three Months Ended		Nine Months Ended
	September 30,		September 30,
	2013	2012	2013	2012
Average number of stock options	—	12,631,000	3,461,000	12,035,000

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