Question: if the anti-dilutive common shares were not excluded from the diluted weighted-average shares outstanding for the year ended december 31 , 2015 , what would the total diluted weighted-average shares outstanding be , in millions?
Evidence:
table_3: ( in millions ) the diluted weighted-average shares outstanding ( 3 ) of years ended december 31 , 2015 is 171.8 ; the diluted weighted-average shares outstanding ( 3 ) of years ended december 31 , 2014 is 172.8 ; the diluted weighted-average shares outstanding ( 3 ) of years ended december 31 , 2013 ( 1 ) is 158.7 ;
text_14: ( 2 ) the dilutive effect of outstanding stock options , restricted stock units , restricted stock , coworker stock purchase plan units and mpk plan units is reflected in the diluted weighted-average shares outstanding using the treasury stock method .
text_15: ( 3 ) there were 0.4 million potential common shares excluded from the diluted weighted-average shares outstanding for the year ended december 31 , 2015 , and there was an insignificant amount of potential common shares excluded from the diluted weighted-average shares outstanding for the years ended december 31 , 2014 and 2013 , as their inclusion would have had an anti-dilutive effect .
