The rights, including the liquidation and dividend rights, of the holders of Class A common stock and Class B common stock are identical, except with respect to voting. As a result, the undistributed earnings are allocated on a proportionate basis and the resulting income or loss per share will, therefore, be the same for both Class A common stock and Class B common stock on an individual or combined basis.
The following potentially dilutive shares were not included in the calculation of diluted shares outstanding as the effect would have been anti-dilutive, or in the case of performance awards, as the issuance of such shares is contingent upon the satisfaction of certain conditions which were not satisfied by the end of the reporting period (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.
