For the quarter s ended July 1, 2018 and July 2, 2017, options and restricted stock units totaling 1,214 and 453, respectively, were excluded from the calculation of diluted earnings per share because to include them would have been antidilutive. For the six-month periods ended July 1, 2018 and July 2, 2017, options and restricted stock units totaling 3,127 and 546, respectively, were excluded from the calculation of diluted earnings per share because to incl ude them would have been antidilutive. Of this amount 1,921 would have been included in the calculation of diluted shares had the Company not had a net loss in the six month period ended July 1, 2018. Assuming that these awards and options were included, u nder the treasury stock method, they would have resulted in an additional 823 shares being included in the diluted earnings per share calculation for the six month period ended July 1, 2018.
