Weighted Average Shares Outstanding represents the time-weighted average number of common shares over a reporting period. It accounts for share issuances, repurchases, and other changes, ensuring per-share metrics like EPS are calculated with a representative share count.
Why are Weighted Average Shares Important?
Weighted Average Shares are crucial because:
Accurate Per-Share Metrics: They ensure earnings per share (EPS) and other per-share ratios reflect the impact of share count changes over time.
Comparability: Using a weighted average prevents distortions when shares are issued or repurchased mid-period.
Transparency: Provides clarity on how share transactions affect shareholder value metrics.
How are Weighted Average Shares Calculated?
To calculate weighted average shares:
Identify all share count changes (issuances, buybacks) during the period.
Determine the portion of the period each share count was outstanding.
Multiply each share balance by the fraction of the period it was outstanding.
Sum the results.
Weighted Average Shares = Σ(Share Count × Time Outstanding Fraction)
For example, if a company had 1 million shares for the first half of the year and issued an additional 200,000 shares at mid-year, the weighted average would be:
