EARNINGS PER SHARE AND SHAREHOLDERS’ EQUITY Earnings per Share Basic earnings per Common Share (“Basic EPS”) is computed by dividing net earnings (the numerator) by the weighted average number of Common Shares outstanding during each period (the denominator). Diluted earnings per Common Share (“Diluted EPS”) is similar to the computation for Basic EPS, except that the denominator is increased by the dilutive effect of vested and unvested stock options, restricted shares and restricted share units computed using the treasury stock method. The following table reconciles the number of Common Shares used to compute Basic EPS and Diluted EPS for the three months ended September 30, 2009 and 2008:   <table border="0" cellspacing="0" cellpadding="0" width="76%" align="center"> <tr> <td width="76%"></td> <td valign="bottom" width="7%"></td> <td></td> <td valign="bottom" width="7%"></td> <td></td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom">  </td> <td style="BORDER-BOTTOM: #000000 1px solid" valign="bottom" colspan="3" align="center">For the Three Months Ended September 30,</td> </tr> <tr> <td valign="bottom" nowrap="nowrap"> (in millions) </td> <td valign="bottom">  </td> <td style="BORDER-BOTTOM: #000000 1px solid" valign="bottom" align="center">2009</td> <td valign="bottom">  </td> <td style="BORDER-BOTTOM: #000000 1px solid" valign="bottom" align="center">2008</td> </tr> <tr bgcolor="#CCEEFF"> <td valign="top"> Weighted-average Common Shares – basic </td> <td valign="bottom">  </td> <td valign="bottom" align="right">359.1</td> <td valign="bottom">  </td> <td valign="bottom" align="right">356.7</td> </tr> <tr> <td valign="top"> Effect of dilutive securities: </td> <td valign="bottom">  </td> <td valign="bottom"></td> <td valign="bottom">  </td> <td valign="bottom"></td> </tr> <tr bgcolor="#CCEEFF"> <td valign="top"> Employee stock options, restricted shares and restricted share units (1) </td> <td valign="bottom">  </td> <td valign="bottom" align="right">—  </td> <td valign="bottom">  </td> <td valign="bottom" align="right">4.4</td> </tr> <tr style="FONT-SIZE: 1px"> <td valign="bottom"></td> <td valign="bottom">  </td> <td style="BORDER-TOP: #000000 1px solid" valign="bottom">  </td> <td valign="bottom">  </td> <td style="BORDER-TOP: #000000 1px solid" valign="bottom">  </td> </tr> <tr> <td valign="top"> Weighted-average Common Shares – diluted </td> <td valign="bottom">  </td> <td valign="bottom" align="right">359.1</td> <td valign="bottom">  </td> <td valign="bottom" align="right">361.1</td> </tr> <tr style="FONT-SIZE: 1px"> <td valign="bottom"></td> <td valign="bottom">  </td> <td style="BORDER-TOP: #000000 3px double" valign="bottom">  </td> <td valign="bottom">  </td> <td style="BORDER-TOP: #000000 3px double" valign="bottom">  </td> </tr> </table>   <table style="BORDER-COLLAPSE: collapse" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr> <td valign="top" width="4%" align="left">(1)</td> <td valign="top" align="left">Due to the Company incurring a loss from continuing operations and a net loss during the first quarter of fiscal 2010, potential dilutive common shares have not been included in the denominator of the dilutive per share computation for the three months ended September 30, 2009 due to their antidilutive effect.</td> </tr> </table> The potentially dilutive employee stock options that were antidilutive for the three months ended September 30, 2009 and 2008 were 22.3 million and 24.9 million, respectively. The total number of Common Shares issued less the Common Shares held in treasury is used to determine the Common Shares outstanding.   Shareholders’ Equity On August 5, 2009, the Company cancelled the previously approved share repurchase program and announced a new $500.0 million share repurchase program which expires on August 31, 2012. The Company expects to use this repurchase program to offset equity plan issuances. During the three months ended September 30, 2009, the Company did not purchase any of its Common Shares under this program. </div> 12.
