Options to purchase 255,000 and 248,000 shares of common stock at an exercise price between $30.38 and $40.88 and between $29.02 and $40.88 per share were outstanding during the third quarter of 2011 and the third quarter of 2010, respectively, but were not included in the computation of diluted earnings per share because the options' exercise price was greater than the average market price of the common shares and therefore, the effect would have been anti-dilutive.
