Options, restricted stock units and warrants included in the computation of diluted earnings per share are calculated using the treasury stock method. For the three-month periods ended September 30, 2018 and 2017, 0.9 million and 0.8 million, and during the nine-month periods ended September 30, 2018 and 2017, 0.8 million and 0.7 million, respectively, of outstanding options and warrants were excluded from the computation of diluted earnings per share due to their having an anti-dilutive effect. Once a restricted stock unit vests, it is included in the computation of weighted average shares outstanding for purposes of basic and diluted earnings per share.
