For the three and nine months ended September 30, 2012, respectively, we excluded 1.9 million share-based awards from the calculation since the effect would have been anti-dilutive.  For the three and nine months ended September 30, 2011, respectively, we excluded 2.9 million and 1.8 million share-based awards from the calculation since the effect would have been anti-dilutive.

The 1.50% Series B Convertible Senior Notes and 1.50% Series C Convertible Senior Notes did not have an effect on the calculation for the periods presented.  See Note 12—Debt.
