NOTE 14 - NET INCOME PER COMMON SHARE
Basic net income per common share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding.

Diluted net income per common share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding plus the incremental number of shares added as a result of converting common stock equivalents, calculated using the treasury stock method. The Corporation's common stock equivalents consist of RSUs and PSUs. PSUs are required to be included in weighted average diluted shares outstanding if performance measures, as defined in each PSU award agreement, are met as of the end of the 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.
