Earnings Per Share [Abstract]

Earnings Per Share

Note 2 – Earnings Per Share

We calculate basic earnings per share (EPS) by dividing net income by the weighted average number of common shares outstanding.  We include outstanding unvested restricted stock awards of our common stock in the basic weighted average share calculation.  Diluted EPS includes the dilutive effects of other share-based awards.  Stock options with exercise prices that are higher than the average market prices of our common stock for the periods presented are excluded from the diluted EPS calculation because their effect is anti-dilutive.

The table below presents the computation of earnings per share, including the reconciliation of basic and diluted weighted average shares outstanding (in thousands, except EPS):
