Given the loss from continuing operations in 2018 and 2016, all options are considered anti-dilutive and were excluded from the calculation of diluted loss from continuing operations per share and diluted net income (loss) per share. Stock options excluded from the calculations of diluted income (loss) from continuing operations per share for the years ended December 31, 2018, 2017, and 2016, had a per share exercise price ranging from $4.42 to $25.16 in each respective year.
