(1)For periods presented with a net loss from continuing operations applicable to common shareholders, weighted average shares for basic earnings per share is also used for calculating diluted earnings per share because all dilutive potential common shares are anti-dilutive and are therefore excluded from the calculation.

Consolidated net income applicable to common shareholders was $1.90 billion in the fourth quarter of 2024 compared to $1.46 billion in the fourth quarter of 2023, primarily due to improved underwriting results from increased earned premium and improved loss trends and higher investment results.
