The following table sets forth the computation of basic earnings per share using the two-class method for amounts attributable to the Company’s shares of Common Stock and Class B Common Stock (in thousands, except per share data):

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 and twenty-six weeks ended February 28, 2015, 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 as it was the more dilutive of the two methods. The following table sets forth the computation of diluted earnings per share of Common Stock for the thirteen and twenty-six weeks ended February 28, 2015 as follows (in thousands, except per share data):
|  | Thirteen weeks |  |  | Twenty-six weeks |
