Earnings per Ordinary Share

Basic earnings per ordinary share are calculated by dividing net income available to holders of Aspen Holdings’ ordinary shares by the weighted average number of ordinary shares outstanding. Net income available to ordinary shareholders is calculated by deducting preference share dividends and net income/(loss) attributable to non-controlling interest from net income/(loss) after tax for the period. Diluted earnings per ordinary share are based on the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the period of calculation using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share for the twelve months ended December 31, 2017, 2016, and 2015, respectively:

_______________


⁽¹⁾	The $8.0 million deduction from net income in 2017 is attributable to the reclassification from additional paid-in capital to retained earnings representing the difference between the capital raised upon issuance of the 7.401% Preference Shares and 7.250% Preference Shares, net of issuance costs, and the final redemption costs of $293.2 million.


⁽²⁾	Dilutive securities consist of employee restricted share units and performance shares associated with the Company’s long term incentive plan, employee share purchase plans and director restricted stock units and options as described in Note 17.


⁽³⁾	The basic and diluted number of ordinary shares for 2017 is the same, as the inclusion of dilutive securities in a loss making period would be anti-dilutive.
