[1] Options to purchase approximately 1,475 shares of common stock that were outstanding during the six months ended September 28, 2012 were not included in the computation of diluted earnings per share because the options’ exercise prices exceeded the average fair market value of the Company’s common stock, and, therefore, inclusion would be anti-dilutive. There were no anti-dilutive options outstanding as of September 30, 2011.
