Earnings Per Share
Basic earnings per share represents income available to common stockholders divided by the weighted average number of common shares outstanding during the reported period. Diluted earnings per share reflects the effect of the increase in shares outstanding determined by using the treasury stock method for awards issued under our incentive stock plans.
As of December 31, 2023, 2022 and 2021, there were less than 1.0 million anti-dilutive weighted stock-based awards outstanding. As of December 31, 2023, 2022 and 2021, there were 0.4 million, 0.2 million and 0.1 million, respectively, of contingently issuable performance-based stock awards outstanding that were excluded from the diluted earnings per share calculation because the contingencies had not been met. Potentially dilutive shares whose effect would have been antidilutive are excluded from the computation of diluted net income per share.
Basic and diluted weighted average shares outstanding and earnings per share were as follows:

About Earnings Per Share Disclosures

The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.

Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
