Equity [Abstract] |
Shareholders' equity | Shareholders’ equity Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed in the same manner except that the weighted average number of shares is increased to include dilutive securities. The following table provides a reconciliation of basic to diluted weighted average number of common shares outstanding:
| Three Months Ended
| March 31, 2019 |  | April 1, 2018
| (Shares in thousands)
Basic | 46,050 |  |  | 45,329 |
Dilutive effect of share-based awards | 892 |  |  | 1,044 |
Dilutive effect of convertible warrants | — |  |  | 322 |
Diluted | 46,942 |  |  | 46,695 |
The weighted average number of shares that were antidilutive and therefore excluded from the calculation of earnings per share were 0.1 million and 0.6 million for the three months ended March 31, 2019 and April 1, 2018, respectively. The following tables provide information relating to the changes in accumulated other comprehensive loss, net of tax, for the three months ended March 31, 2019 and April 1, 2018:
