(a) 
For the three months ended September 30, 2018 and 2017, 0.5 million and 0.7 million non-vested stock awards, respectively, have an anti-dilutive effect and therefore are excluded from the computation of diluted weighted average shares outstanding. For the nine months ended September 30, 2018 and 2017, 0.2 million and 0.8 million non-vested stock awards, respectively, have an anti-dilutive effect and therefore are excluded from the computation of diluted weighted average shares outstanding.
