Basic earnings per share ("EPS") amounts are calculated by dividing earnings available to common stockholders by the weighted average number of common shares outstanding. Diluted EPS is calculated by dividing net income attributable to common shareholders by the weighted average number of common and dilutive common equivalent shares outstanding during the period. Beginning in 2026, due to the previous conversion of all preferred stock to common, dilutive common equivalent shares are calculated using the if-converted method. In prior periods, dilutive common equivalent shares are calculated using the more dilutive of either the if-converted or two-class methods.
