[1] The Company’s effective tax rate for 2017, 2016, and 2015 is not consistent due to the re-measurement of the deferred tax assets, impairment of goodwill not deductible for tax purposes, 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 2017, 2016, and 2015. See Part II. Item 8. “Financial Statements and Supplementary Data - Note 17: Income Taxes” for additional details.

[2] The Holding Company and Eliminations calculation of Net Income attributable to the Company includes net income from Discontinued Operations for the years ended December 31, 2017, 2016 and 2015 of $4.9 million, $5.5 million, and $6.4 million, respectively

[3] The Company presents its EPS based on the treasury stock method. The Company reverted to the treasury stock presentation from the two-class presentation due to the immaterial number of participating shares outstanding as of March 31, 2016. There is no difference between the calculation of EPS based on the treasury stock method and the calculation of EPS based on the two-class method for the year ended December 31, 2017.If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the year ended December 31, 2016. Net income attributable to common shareholders would have been reduced by an additional $4 thousand, for the year ended December 31, 2016. The allocation of net income to participating securities would have been $8 thousand for the year ended December 31, 2016, reducing net income attributable to common shareholders by a total of $12 thousand for the same period. Basic EPS would not change. Weighted average diluted shared outstanding would have been reduced by 7,185 shares for the year ended December 31, 2016. Diluted EPS would not change. If the EPS presentation had been based on the two-class method, the following adjustments would have been made to the presentation of EPS for the year ended December 31, 2015. Net income attributable to common shareholders would have been reduced by an additional $90 thousand for the year ended December 31, 2015, and the allocation of net income to participating securities would have been $92 thousand for the same period, reducing net income attributable to common shareholders by a total of $182 thousand, for the same period. Total basic EPS and basic EPS from continuing operations would each decrease by $0.01 per share for the year ended December 31, 2015. Weighted average diluted shares outstanding would have been reduced by 167,937 shares for the same period. Diluted EPS would not change.

[4] The diluted EPS computations for the years ended December 31, 2017, 2016, and 2015 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, 2017 2016 2015Shares excluded due to anti-dilution (treasury stock 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, 2017 2016 2015Shares 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)67 270 548Total shares excluded due to exercise price exceeding the average market price of common shares during the period67 270 548(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.
