Weighted average shares outstanding - basic	1,357.6	1,341.2	1,324.3

Weighted average shares outstanding - assuming dilution	1,377.2	1,341.2	1,324.3

Our weighted-average shares outstanding for earnings per share calculations excluded common stock equivalents of 22 million in 2015 and 24 million in 2014 due to our net loss positions.

Weighted-average shares outstanding, assuming dilution, excludes the impact of less than 1 million stock options for 2016, 2 million stock options for 2015 and 12 million stock options for 2014, due to the exercise prices of these stock options being greater than the average fair market value of our common stock during the year.
