UnitedHealth Group strongly encourages employees and contractors to raise possible ethics and compliance issues. UnitedHealth Group offers several channels for employees and third parties to
report ethics and compliance concerns or incidents, including, without limitation, concerns about accounting, internal controls, or auditing matters. We provide a Compliance HelpLine that is available to employees 24 hours a day, 7 days a week with live operators who can connect to translators in multiple languages. Individuals may choose to remain anonymous. In addition, employees and contractors may also raise their ethics and compliance concerns with UnitedHealth Groups Ethics and Integrity Office, their manager, the Human Capital department, or the Corporate Security department. We prohibit retaliatory action against any individual for raising legitimate concerns or questions regarding ethics and compliance matters or for reporting suspected violations. Calls to the Compliance HelpLine are received by a third party vendor, which reports the calls to UnitedHealth Groups Ethics and Integrity Office for review and investigation.
