Net Income Per Share
Consolidated basic earnings per share excludes the dilutive effect of common stock equivalents and is computed by dividing net income available to common stockholders by the weighted-average number of common shares actually outstanding for the year. Diluted earnings per share is similarly calculated with the inclusion of dilutive common stock equivalents. The following table reconciles net income and the number of shares used in the basic and diluted earnings per share calculations.

(a)    In calculating earnings per share, accounting standards require that common shares owned by the ORI 401(k) Plan that are unallocated to participants in the plan be excluded from the calculation.

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.
