| Three Months Ended March 31,
(in millions) | 2020 |  | 2019
Weighted average shares outstanding - basic | 1,397.4 |  |  | 1,387.7 |
Net effect of common stock equivalents | 16.1 |  |  | 20.7 |
Weighted average shares outstanding - assuming dilution | 1,413.5 |  |  | 1,408.4 |
Stock options outstanding of six million for the first quarter of 2020 and three million for the first quarter of 2019 were excluded from weighted average shares outstanding - assuming dilution because exercise prices were greater than the average fair market value of our common stock for the related periods. We issued approximately four million shares of our common stock in the first quarter of 2020 and approximately six million shares of our common stock in the first quarter of 2019, following the exercise of stock options, vesting of deferred stock units or purchases under our employee stock purchase plan. We did not repurchase any shares of our common stock in the first quarter of 2020 or 2019.
