Maintain confidential reporting via hotline or similar means

Establish the toll-free integrity hotline and Corporate Integrity Program post office address, so that employees have every opportunity to report concerns or possible wrongdoing regarding corporate integrity issues.

Treat calls to the hotline confidentially, and will not be traced. Similarly, handle written communications to the Corporate Integrity Program post office address confidentially, and the author need not provide his or her name.
