Earnings Per Share [Abstract]

Earnings Per Share

18. Earnings Per Share

Basic earnings per share is calculated by dividing net earnings after noncontrolling interest by the weighted average shares outstanding. Diluted earnings per share is calculated similarly, except that it includes the dilutive effect of the assumed redemption of OP Units for shares on common stock of InfraREIT, Inc. or common shares of InfraREIT, L.L.C., as applicable, if such redemption were dilutive. The redemption of OP Units would have been anti-dilutive during the three months ended March 31, 2015 and 2014.

Earnings per share are calculated as follows:
