The number of shares used to calculate diluted earnings (loss) per share is based on the number of common shares used to calculate basic earnings (loss) per share plus the dilutive effect of stock options and other stock-based instruments held by the Company’s employees and directors during each period and the Convertible Notes when these are convertible into the Company’s common stock. The Convertible Notes, which were issued in April 2008, become dilutive for earnings per share calculations when the average share price for the quarter exceeds the conversion price of $54.66. The shares that would be issued to settle the conversion spread are included in the diluted earnings per share calculation when the conversion option is in the money. For the year ended December 31, 2009, the conversion option for the Convertible Notes was not in the money, and therefore there was no dilutive earnings per share impact. For the year ended December 31, 2008, there were 734,613 shares included in the computation of year-to-date diluted earnings per share for the period when the Convertible Notes were in the money during the year. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The following table provides a reconciliation of weighted-average shares outstanding used in the basic and diluted earnings per share computations for the periods presented: </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%">  <tr valign="bottom"> <td width="58%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="10" style="border-bottom: 1px solid #000000"><b>Years Ended December 31,</b></td> <td> </td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000"><b>2009</b></td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000"><b>2008</b></td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000"><b>2007</b></td> <td> </td> </tr>   <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Weighted average shares — basic </div></td> <td> </td> <td> </td> <td align="right">90,662,718</td> <td> </td> <td> </td> <td> </td> <td align="right">68,453,724</td> <td> </td> <td> </td> <td> </td> <td align="right">64,631,507</td> <td> </td> </tr> <tr valign="bottom" style="padding-top: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">Dilutive effect of stock equivalents </div></td> <td> </td> <td> </td> <td align="right">1,039,910</td> <td> </td> <td> </td> <td> </td> <td align="right">1,806,011</td> <td> </td> <td> </td> <td> </td> <td align="right">377,923</td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Weighted average shares- diluted </div></td> <td> </td> <td> </td> <td align="right">91,702,628</td> <td> </td> <td> </td> <td> </td> <td align="right">70,259,735</td> <td> </td> <td> </td> <td> </td> <td align="right">65,009,430</td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr>  </table> </div> </div>  <!-- Begin Block Tagged Note false false No definition available.
