The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period. These outstanding stock awards are not included in the computation of diluted earnings per share because the effect would be anti-dilutive.  For the quarter ended September 30, 2011, there were 6.5 million anti-dilutive stock awards excluded from the computation.  For the nine months ended September 30, 2011, there were no anti-dilutive stock awards excluded from the computation.  The number of stock awards excluded from the computation was 12.7 million and 12.6 million for the quarter and nine months ended September 30, 2010, respectively.
