The calculations of diluted income from continuing operations per share for the three-month periods ended September 30, 2017 and 2016, exclude 0.8 million and 0.6 million potentially dilutive stock options, which had the effect of being anti-dilutive. The calculations of diluted income from continuing operations per share for the nine-month periods ended September 30, 2017 and 2016, exclude 0.8 million and 0.8 million potentially dilutive stock options, which had the effect of being anti-dilutive. Given the loss from continuing operations for the three-month and nine-month periods ended September 30, 2017, and for the nine-month period ended September 30, 2016, all options are considered anti-dilutive and were excluded from the calculation of diluted loss from continuing operations per share.
