Stock-based awards | 238,226 |  |  | 239,540 |  |  | 245,633 |  |  | 256,269 |
0.75% convertible senior notes due 2021(1) (2) | 601,349 |  |  | 5,005,734 |  |  | 2,116,093 |  |  | 5,005,734 |
Warrants(1) (2) | 601,349 |  |  | 5,005,734 |  |  | 2,116,093 |  |  | 5,005,734 |
Total | 1,440,924 |  |  | 10,251,008 |  |  | 4,477,819 |  |  | 10,267,737 |
(1) Under the treasury stock method, our 0.75% convertible senior notes (“Notes”) will have a dilutive impact on earnings per common share if our average stock price for the period exceeds the $96.89 per share conversion price. Our average stock price did not exceed the per share conversion price during the three or nine months ended October 24, 2020; therefore, there was no dilutive impact on earnings per common share for these periods. The warrants associated with our Notes will have a dilutive impact on earnings per common share if our average stock price for the period exceeds the $130.43 per share warrant strike price. As our average stock price did not exceed the strike price for the warrants for any of the periods presented, the underlying common shares were anti-dilutive as reflected in the table above. (2) In connection with the purchase of $401.7 million of the Notes in fiscal 2021 and $25.0 million in fiscal 2020, we unwound convertible note hedge transactions and warrants proportionately to the number of Notes, resulting in a decrease in the number of excluded weighted shares.
