(a)Restructuring costs in 2020 primarily related to simplification and other cost saving initiatives implemented in fiscal 2020, while 2019 and 2018 included expenses related to the Company's acquisition of CareFusion in fiscal year 2015 and other initiatives.

(b)Expenses in 2020, 2019 and 2018 largely represented the costs associated with the conversion of certain pre-acquisition equity awards of Bard which, to encourage post-acquisition employee retention, were converted to BD equity awards with substantially the same terms and conditions as were applicable under such Bard awards immediately prior to the acquisition date.  Expenses in 2018 also included costs relating to Bard’s pension plan, partially offset by a gain on the sale of the Company's soft tissue core needle biopsy product line recorded in fiscal year 2018.
