Weighted Average Common Shares
We calculate net income per common share - basic using the two class method. We calculate net income per common share - diluted using the more dilutive of the two class or treasury stock method. Unvested share awards are considered participating securities and the related impact on earnings are considered when calculating net income per common share - basic and net income per common share - diluted.
The calculation of net income per common share - basic and diluted is as follows (amounts in thousands, except per share data):

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.
