Incremental shares of 504,000, 448,000, and 685,000 for 2011, 2010, and 2009, respectively, were excluded from the computation of the diluted earnings per common shares due to their anti-dilutive effect. Potentially dilutive securities representing approximately 103,000, 93,000, and 74,000 shares of common stock for 2011, 2010, and 2009, respectively, were also excluded from the computation of diluted earnings per common share because their effect would have been anti-dilutive.
