EARNINGS PER SHARE

A reconciliation of both calculations is presented in the following table as of December 31:

Options to purchase approximately 5 million shares and 4 million shares of common stock in 2010 and 2009, respectively, were not included in the computation of diluted earnings per share because the options’ exercise price was greater than the average market price of the common shares, thus making these options anti-dilutive.
