For the three months ended September 30, 2012 and 2011, stock options for 0.9 million and 1.0 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive. For the nine months ended September 30, 2012 and 2011, stock options for 1.5 million and 0.9 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive.
