If a company has multiple common share classes, how should you treat them when calculating diluted shares?

• A. Treat all classes as one.
• B. Only consider the largest class.
• C. Add shares from all classes to basic and diluted totals.
• D. Exclude non-voting classes.

Answer: (C)

Diluted earnings per share adds up all shares that could dilute existing holders. If there are multiple classes of common stock, each class represents a claim on earnings and could become more shares through conversion or other dilutive actions. So you should combine all common shares across classes when forming the baseline count (basic) and then include any additional shares from potential conversions to form the diluted count. That’s why adding shares from all classes to both basic and diluted totals gives the correct denominator for diluted EPS. Ignoring some classes or treating only one class would understate the share count and distort the dilution calculation. Non-voting common stock is still common equity, so excluding it would also misstate the denominator.
