[1] The Company’s effective tax rate for 2015, 2014, and 2013 are not consistent due to earnings from tax-exempt investments, non-deductible compensation, state and local taxes, income tax credits and income attributable to noncontrolling interests having a different impact on the effective tax rate due primarily to the different levels of income before taxes in years 2015, 2014, and 2013. See Part II. Item 8. “Financial Statements and Supplementary Data - Note 17: Income Taxes” for additional details.

[2] The diluted EPS computations for the years ended December 31, 2015, 2014, and 2013 do not assume the conversion, exercise or contingent issuance of the following shares for the following periods because the result would have been antidilutive for the periods indicated. As a result of the anti-dilution, the potential common shares excluded from the diluted EPS computation are as follows: For the year ended December 31, 2015 2014 2013Shares excluded due to anti-dilution (treasury method):(In thousands)Potential common shares from: Convertible trust preferred securities (a)1 1 1Total shares excluded due to anti-dilution1 1 1 For the year ended December 31, 2015 2014 2013Shares excluded due to exercise price exceeding the average market price of common shares during the period (total outstanding):(In thousands)Potential common shares from: Options, restricted stock, or other dilutive securities (b)548 829 1,399Total shares excluded due to exercise price exceeding the average market price of common shares during the period548 829 1,399(a) If the effect of the conversion of the trust preferred securities would have been dilutive, an immaterial amount of interest expense, net of tax, related to the convertible trust preferred securities would have been added back to net income attributable to common shareholders for the diluted EPS computation for the years presented.(b)Options to purchase shares of common stock, non-participating performance- and certain time-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.
