8. Stock Options and Stock Awards

        The Company recognizes share-based compensation expense over the requisite service period of the award, net of an estimate for the impact of forfeitures. Operating results for the twenty-six week periods ended September 1, 2012 and August 27, 2011 include $8,653 and $7,523, respectively, of compensation costs related to the company's stock-based compensation arrangements.

        The total number and type of newly awarded grants and the related weighted average fair value for the thirteen week periods ended September 1, 2012 and August 27, 2011 are as follows:

        Typically, stock options granted vest, and are subsequently exercisable in equal annual installments over a four-year period for employees. During fiscal 2012, certain employee stock options and awards were issued that vest 50% in year 3 and 50% in year four. Stock awards granted to non-employee directors vest 80% in year one, 10% in year two and 10% in year three.

        The Company calculates the fair value of stock options using the Black- Scholes-Merton option pricing model. The following assumptions were used in the Black-Scholes-Merton option pricing model:
