The Company is required to calculate diluted EPS for Common Stock using the more dilutive of the following two methods:
| • |  | The treasury stock method; or
| • |  | The two-class method assuming a participating security is not exercised or converted.
For the thirteen weeks ended November 30, 2013 and November 24, 2012, the Company’s diluted EPS assumes the conversion of all vested Class B Common Stock into Common Stock and uses the two-class method for its unvested participating shares. The following table sets forth the computation of diluted earnings per share of Common Stock for the thirteen weeks ended November 30, 2013 and November 24, 2012 as follows (in thousands, except per share data):
|  | Thirteen weeks ended November 30, 2013 |  |  | Thirteen weeks ended November 24, 2012 |
|  | Earnings to Common shareholders |  |  | Common Shares |  |  | EPS |  |  | Earnings to Common shareholders |  |  | Common Shares |  |  | EPS |

Share-based awards that would result in the issuance of 160 shares of Common Stock were excluded from the calculation of diluted earnings per share for the thirteen weeks ended November 30, 2013 because they were anti-dilutive. There were no share-based awards that were excluded from the calculation of diluted earnings per share for the thirteen weeks ended November 24, 2012 because they were anti-dilutive.
