Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. The diluted net income per share is computed using the weighted-average number of common shares outstanding and dilutive potential common shares outstanding during the period. Dilutive common shares outstanding includes the dilutive effect of in-the-money options, unvested RSUs (including market conditions-based RSUs), and unvested PSUs when the performance condition is met and ESPP contributions. The dilutive effect of such equity awards is calculated based on the average share price for each fiscal period using the treasury stock method.
Certain potential common shares were excluded from our calculation of weighted-average common shares outstanding - diluted because either they would have had an anti-dilutive effect on net income per share or they were related to shares from PSUs or from market conditions-based RSUs that were contingently issuable and the contingency had not been satisfied at the end of the reporting period.
The weighted-average potential common shares excluded from our calculation were as follows (in thousands):

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.
