[1] Based on the annual impairment review of goodwill performed as of the first day of our fourth quarter in 2015 and due to the failure of the tomato and vegetable business in North America to meet our expectations, we wrote-off $66.1 million of goodwill for the quarter ended January 1, 2016, which was related to the 2003 tomato and vegetable business acquisition.

[2] Diluted earnings per share for the quarter ended December 26, 2014 excludes the impact of antidilutive share-based payment awards for 399,568 ordinary shares, as they were antidilutive.
