Earnings Per Share
Restricted stock awards granted as part of the Company's Incentive Compensation Program participate in nonforfeitable dividends on a one-to-one per-share ratio with common stock. As such, unvested restricted stock awards are considered participating securities in the computation of earnings per share under the two-class method, and undistributed earnings are allocated between common stock and participating securities on a one-to-one per-share basis. The numerator in the computation of basic and diluted earnings per share excludes income allocated to these participating securities.
The denominator in the computation of diluted earnings per share includes the dilutive effect of stock options and performance share awards granted as part of the Company's Incentive Compensation Program. The dilutive effect of stock options is calculated using the treasury stock method when the average market price of the Company's common shares during the reporting period exceeds the exercise price of the options. Performance shares are contingently issuable, and the dilutive effect is based on the number of shares that would have been awarded had the conditions at the end of the reporting period continued until the end of the performance period.

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.
