Code of Business Conduct & Ethics

The Corporate Code of Business Conduct and Ethics (Code) serves as the foundation for ethical behavior across our company. The Code is an extension of our core values, especially our core value of Integrity. Not only is Integrity a core value of The Principal, it is the foundation upon which our Code is built.

Effective June 1, 2010, the company's Board of Directors, upon the recommendation of the Nominating and Governance Committee, approved a revised and updated Corporate Code of Business Conduct and Ethics, which contains the Company's code of ethics as defined in Item 406(b) of Regulation S-K. The revised and updated Code reflects technical and administrative amendments as well as the addition of brief descriptions of Company policies and procedures not previously included in the Code.
