We generated net losses in 2010 and 2009. Our weighted-average shares outstanding for earnings per share calculations excluded common stock equivalents of 10 million for 2010 and 8 million for 2009 due to our net loss position in these years.
Weighted-average shares outstanding, assuming dilution, also excludes the impact of 62 million stock options for 2011, 61 million for 2010, and 48 million for 2009, due to the exercise prices of these stock options being greater than the average fair market value of our common stock during the year.
