Basic loss per share was calculated by dividing our net loss by the weighted average number of common shares outstanding during the year, excluding restricted shares which are considered to be contingently issuable.  To calculate diluted earnings per share, common share equivalents would be added to the weighted average number of common shares outstanding.  Common share equivalents would be computed based on the number of outstanding options to purchase common stock and unvested restricted shares, as calculated using the treasury stock method.  However, in years when we have a net loss, or the exercise price of stock options by grant are greater than the actual stock price as of the end of the year, those common share equivalents are anti-dilutive and we exclude them from our calculation of our per share amounts.  As we had a net loss for the years ended December 30, 2011, December 31, 2010 and December 25, 2009, we did not include any common stock equivalents in the calculation of diluted earnings per share.  There were approximately 1,252,000, 157,000 and 82,000 stock options outstanding as of December 30, 2011, December 31, 2010 and December 25, 2009, respectively.  Also, we had unvested restricted shares outstanding of approximately 580,000, 420,000 and 330,000 as of December 30, 2011, December 31, 2010 and December 25, 2009, respectively.

The dilutive effect of our convertible senior notes is also included in our diluted earnings per share calculation using the if-converted method.  Interest attributable to the convertible senior notes, net of tax, is added back to our net earnings for the period, and the total shares that would be converted if the notes were settled at the end of the period are added to the weighted average common shares outstanding.  However, in periods when we have a net loss or the amount of interest attributable to the convertible senior notes, net of tax, per the potential common shares obtainable in a conversion exceeds our basic earnings per share, the overall effects of the convertible senior notes are anti-dilutive and are excluded from the calculation of diluted earnings per share.  For the years ended December 30, 2011, December 31, 2010, and December 25, 2009, the effect of our convertible senior notes were anti-dilutive, so they were excluded from the calculation of diluted earnings per share.
 
Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are required to be treated as participating securities. Under our restricted stock plan, non-forfeitable dividends were paid on unvested shares of restricted stock. We discontinued the payment of dividends following the dividend paid on October 21, 2011. This condition meets the qualifications of participating securities and requires the two-class method of calculating earnings per share to be applied.  We have calculated basic and diluted earnings per share under both the treasury stock method and the two-class method, and there were no significant differences in the per share amounts calculated under the two methods for the years ended December 30, 2011, December 31, 2010 and December 25, 2009.  Therefore, we have not provided the reconciliation of earnings per share under the two class method for any period presented.
 
For the years ended December 30, 2011, December 31, 2010 and December 25, 2009, our loss per share calculations were as follows (in thousands, except per share amounts):
