Accounting Irregularities

Northrop Grumman Ethics and Business Conduct

The Sarbanes-Oxley Act of 2002 requires the Audit Committee of the Board of Directors to establish procedures to receive employees' confidential or anonymous concerns regarding questionable accounting or auditing matters.

While the OpenLine is one channel for reporting already in place, any employee with a concern about a financial, accounting or auditing matter can write directly to:

Chair, Audit Committee
Northrop Grumman Board of Directors
c/o Corporate Ethics Office
2980 Fairview Park Drive
Falls Church, VA 22042

Mail will be delivered unopened to the Chair of the Audit Committee. Concerns dealing with other than finance, accounting or audit will be returned to the Ethics Office OpenLine process.
