(In millions)	2013		2012		2013		2012

For the three months ended June 30, 2013 and 2012, stock options for 0.9 million and 1.7 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive. For the six months ended June 30, 2013 and 2012, stock options for 0.7 million and 1.5 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive.
