Our Commitment to Integrity

We know corporate governance is more than meeting the requirements of the law. Confidence and trust must be earned.

Integrity is the cornerstone for our dealings with customers, employees, stockholders, suppliers, competitors and the communities we serve. There can be no exceptions or compromises.

We strive to provide timely and accurate information to stakeholders to establish realistic expectations about our company. Above all, we know we must operate with integrity.

The MDU Resources “Leading with Integrity Guide” is the foundation for our conduct as employees and a corporation. “Leading With Integrity” is the ethics, code of conduct and legal compliance program for MDU Resources.
