Diluted earnings per share is calculated as (Net income minus preferred dividends) divided by (weighted-average shares plus potential shares). Why is this metric important?

• A. It shows best-case earnings per share
• B. It shows worst-case earnings per share
• C. It shows current year earnings per share only
• D. It excludes preferred dividends

Answer: (B)

Diluted earnings per share focuses on the downside scenario for earnings per share by assuming every potential share is issued. The numerator subtracts preferred dividends from net income to reflect the earnings actually available to common shareholders, since those dividends go to preferred holders and aren’t available to common ones. The denominator adds the actual weighted-average shares to the number of potential shares from dilutive instruments (like options, warrants, or convertible securities), capturing how much the share count could grow if those instruments were exercised or converted. Because more shares share the same earnings, diluted EPS tends to be lower than basic EPS when dilution exists, giving investors a conservative view of profitability per share. If there are no dilutive securities, diluted EPS equals basic EPS.
