[1] (2)The diluted EPS computations for the three and nine months ended September 30, 2012 and 2011 do not assume the conversion, exercise, or contingent issuance of the following shares for these periods because the result would have been anti-dilutive for the periods indicated. As a result of the anti-dilution, the potential common shares excluded from the diluted EPS computation are as follows: Three months ended September 30, Nine months ended September 30, 2012 2011 2012 2011Shares excluded due to anti-dilution (treasury method):(In thousands)Potential common shares from: Convertible trust preferred securities (a)784 1,707 784 1,707Total shares excluded due to anti-dilution784 1,707 784 1,707 Three months ended September 30, Nine months ended September 30, 2012 2011 2012 2011Shares excluded due to exercise price exceeding the average market price of common shares during the period (total outstanding):(In thousands)Potential common shares from: Stock options, performance-based restricted stock, or other dilutive securities (b)2,102 3,967 2,180 3,834Warrants (c)— 2,888 — 2,888Total shares excluded due to exercise price exceeding the average market price of common shares during the period2,102 6,855 2,180 6,722(a) If the effect of the conversion of the trust preferred securities would have been dilutive, interest expense, net of tax, related to the convertible trust preferred securities of $0.2 million and $0.4 million for the three months ended September 30, 2012 and 2011, respectively, and of $0.8 million and $1.2 million for the nine months ended September 30, 2012 and 2011, respectively, would have been added back to net income/ (loss) attributable to common shareholders for diluted EPS computations for the periods presented.(b)Options to purchase shares of common stock, non-participating (performance-based) restricted stock, and other dilutive securities that were outstanding at period ends were not included in the computation of diluted EPS or in the above anti-dilution table because their exercise or conversion prices were greater than the average market price of the common shares during the respective periods. (c)Certain warrants to purchase shares of common stock that were outstanding at period ends were not included in the computations of diluted EPS because the warrants' exercise price was greater than the average market price of the common shares during the respective period.
