There were 0.4 million and 0.7 million options outstanding during the three months ended September 30, 2011 and 2010, respectively, and 0.3 million and 0.7 million options outstanding during the nine months ended September 30, 2011 and 2010, respectively, that were not included in the computation of diluted earnings per share because the impact of including such options would be anti-dilutive.
