For fiscal 2014, the $41 million reduction in the post-retirement medical plan obligation was due to changes made to the Company's retiree medical plans during the first quarter of fiscal 2014. The reduction was recognized in Other comprehensive income during the period and will be amortized over the remaining expected life of the plans' participants as actuarially determined.
