The calculations of diluted income from continuing operations per share for the three-month periods ended March 31, 2018 and 2017, exclude 0.5 million and 0.6 million potentially dilutive stock options, which had the effect of being anti-dilutive. Given the loss from continuing operations for the three-month period ended March 31, 2018, all options are considered anti-dilutive and were excluded from the calculation of diluted loss from continuing operations per share.
