| For the Three Months Ended

Net income available to common stockholders (numerator) | $ | 17,231 |  |  | $ | 38,796 |
Weighted-average number of common shares (denominator) | 31,190,366 |  |  | 31,357,124 |
Basic earnings per common share | $ | 0.55 |  |  | $ | 1.24 |
Weighted-average number of common shares | 31,190,366 |  |  | 31,357,124 |
Potential shares of common stock arising from stock options, and unvested restricted share units | 602,549 |  |  | 552,802 |
Potential shares of common stock issuable on conversion of 0.75% convertible senior notes due 2021(1) | 614,999 |  |  | — |

Diluted earnings per common share | $ | 0.53 |  |  | $ | 1.22 |
Anti-dilutive weighted shares excluded from the calculation of earnings per common share:
Stock-based awards | 80,847 |  |  | 96,020 |
0.75% convertible senior notes due 2021 | 4,390,735 |  |  | 5,005,734 |
Warrants | 5,005,734 |  |  | 5,005,734 |
Total | 9,477,316 |  |  | 10,107,488 |
(1) Under the treasury stock method, the convertible senior notes will have a dilutive impact on earnings per common share if the Company’s average stock price for the period exceeds the conversion price for the convertible senior notes of $96.89 per share. The warrants associated with the Company’s convertible senior notes will have a dilutive impact on earnings per common share if the Company’s average stock price for the period exceeds the warrant strike price of $130.43 per share. For the three months ended April 28, 2018, the Company’s average stock price of $110.46 exceeded the conversion price for the convertible senior notes. As a result, shares presumed to be issuable under the convertible senior notes that were dilutive during the period are included in the calculation of diluted earnings per share for the three months ended April 28, 2018. As the Company’s average stock price did not exceed the strike price for the warrants, the underlying common shares were anti-dilutive as reflected in the table above. In connection with the offering of the convertible senior notes, the Company entered into convertible note hedge transactions with counterparties for the purpose of reducing the potential dilution to common stockholders from the conversion of the notes and offsetting any potential cash payments in excess of the principal amount of the notes. Prior to conversion, the convertible note hedge is not included for purposes of the calculation of earnings per common share as its effect would be anti-dilutive. Upon conversion, the convertible note hedge is expected to offset the dilutive effect of the convertible senior notes when the average stock price for the period is above $96.89 per share. See Note 13, Debt, for additional information related to the Company’s convertible senior notes, warrant transactions, and hedge transactions.
