Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

Becton, Dickinson and Company (“BD”) is filing herewith updated financial statements and other affected financial information for the periods included in the BD’s Annual Report on Form 10-K for the fiscal year ended September 30, 2014 (the “Form 10-K”). These financial statements and other affected financial information have been updated to reflect changes made in fiscal year 2015 to BD’s reportable operating segment data.

Effective October 1, 2014, BD’s organizational structure was realigned to better complement its customer-focused solutions strategy and is based upon two principal business segments: BD Medical (“Medical”) and BD Life Sciences (“Life Sciences”). The composition of the Medical segment remains unchanged from its historical composition. The Life Sciences segment consists of the former BD Diagnostics and BD Biosciences segments. Beginning on October 1, 2014, decisions about resource allocation and performance assessment are made separately for the Medical and Life Sciences segments. BD’s two principal business segments are strategic businesses that are managed separately because each one develops, manufactures and markets distinct products and services. BD evaluates performance of its business segments and allocates resources to them primarily based upon operating income.

BD has updated the applicable items that were contained in the Form 10-K reflecting the above mentioned changes in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8, “Financial Statements and Supplementary Data” in Exhibits 99.1 and 99.2 filed in this Current Report, respectively. The information included in this Current Report is presented for information purposes only in connection with the changes in BD’s reportable operating segment data. All other information in the Form 10-K remain unchanged and this Current Report should be read in conjunction therewith. This Current Report does not reflect events occurring after BD filed the Form 10-K and does not modify or update the disclosures therein in any way, other than as noted above. BD began to report comparative results reflective of the above mentioned changes with the filing of BD’s Quarterly Report on Form 10-Q for the quarter ended December 31, 2014, filed with the Securities and Exchange Commission on February 6, 2015.
