Mistaken idea “Basic EPS uses ending common shares”

Mistaken reasoning: This mistake assumes that basic EPS uses ending common shares.

Why this is mistaken

Basic EPS uses ending common shares. Use time-weighted outstanding shares and the supported common numerator, including a two-class allocation when required.

Where to watch
