Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share The following table sets forth the computation of basic and diluted earnings per common share for 2022, 2021 and 2020:
(In thousands, except per share data) |  |  |  | 2022 |  | 2021 |  | 2020
Net income |  |  |  | $ | 509,682 |  |  | $ | 466,151 |  |  | $ | 292,990 |
Less: Preferred stock dividends |  |  |  | 27,964 |  |  | 27,964 |  |  | 21,377 |
Net income applicable to common shares |  | (A) |  | $ | 481,718 |  |  | $ | 438,187 |  |  | $ | 271,613 |
Weighted average common shares outstanding |  | (B) |  | 59,205 |  |  | 56,994 |  |  | 57,523 |
Effect of dilutive potential common shares: |  |  |  |  |  |  |  |
Common stock equivalents |  |  |  | 886 |  |  | 792 |  |  | 496 |
Weighted average common shares and effect of dilutive potential common shares |  | (C) |  | 60,091 |  |  | 57,786 |  |  | 58,019 |
Net income per common share: |  |  |  |  |  |  |  |
Basic |  | (A/B) |  | $ | 8.14 |  |  | $ | 7.69 |  |  | $ | 4.72 |
Diluted |  | (A/C) |  | 8.02 |  |  | 7.58 |  |  | 4.68 |
Potentially dilutive common shares can result from stock options, restricted stock unit awards and shares to be issued under the ESPP and the DDFS Plan, being treated as if they had been either exercised or issued, computed by application of the treasury stock method. While potentially dilutive common shares are typically included in the computation of diluted earnings per share, potentially dilutive common shares are excluded from this computation in periods in which the effect would reduce the loss per share or increase the income per share.
