[1] Excludes outstanding options to purchase shares of common stock because these options had exercise prices in excess of the average market price of our common stock during the period and therefore the effect of including these options would be antidilutive. These options totaled 2,091 and 1,387 for the three- and six-month periods ended July 5, 2015, and 4,491 and 2,922 for the three- and six-month periods ended June 29, 2014, respectively.
