In the US, Zeneca Inc., and/or its indemnitees, have been named as potentially responsible parties (PRPs) or defendants at approximately 15 sites
where Zeneca Inc. is likely to incur future environmental investigation, remediation, operation and maintenance costs under federal, state, statutory
or common law environmental liability allocation schemes (together, US Environmental Consequences). Similarly, Stauffer Management
Company LLC (SMC), which was established in 1987 to own and manage certain assets of Stauffer Chemical Company acquired that year,
and/or its indemnitees, have been named as PRPs or defendants at 33 sites where SMC is likely to incur US Environmental Consequences.
AstraZeneca has also given indemnities to third parties for a number of sites outside the US. These environmental liabilities arise from legacy
operations that are not currently part of the Group’s business and, at most of these sites, remediation, where required, is either completed or
nearing completion.
