A reconciliation of the weighted average shares used in the basic and diluted earnings per common share computations for the years ended December 31, 2017, 2016 and 2015 is presented below (in thousands):

	2017	2016	2015
Weighted-average shares outstanding:
Basic	566,782	587,874	566,448
Dilutive securities	10,359	11,945	11,310
Diluted	577,141	599,819	577,758

For the years ended December 31, 2017, 2016 and 2015, options and awards outstanding totaling 7.9 million shares, 5.7 million shares and 3.0 million shares, respectively, were excluded from the calculations as their effect would have been antidilutive.
