Earnings Per Share [Abstract] |
Earnings (Loss) Per Share Data | Earnings (Loss) Per Share Data Earnings (loss) per share is based on weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the impact of dilutive securities and is computed by dividing Net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. The following table presents the income and share data used in the basic and diluted earnings per share computations.

Prior period amounts have been adjusted to reflect application of the new guidance. Excluded from the calculation of diluted earnings (loss) per share is the impact of potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans that would have been antidilutive during the respective periods. The Company repurchased 550,000 and 445,000 shares of CNAF common stock at an aggregate cost of $24 million and $21 million during the six months ended June 30, 2023 and 2022.
