Tone at the Top: Why Integrity Matters

Ethics and Compliance are Top Priorities at Teradata

Teradata is accelerating the pace of change throughout the company to deliver on our mission to transform how businesses work and people live through the power of data.

As we execute against our strategy and make improvements throughout the organization, we must continue to support our top priorities of ethics, compliance, trust, and integrity.

To help foster and achieve our commitment to Ethics and Compliance, we have declared and communicated our Code of Conduct. Guided by these principles and standards, Teradata people are expected to comply with company controls, policies, and our Code of Conduct—essentially to do the right thing in the right way at all times. Complying with our Code is also part of our commitment to make a meaningful contribution to our community and our world.

Our Code of Conduct provides clear and consistent rules for all to follow, helps ensure that we operate safely, honestly, and legally, and helps Teradata remain a great place to work. Strong ethics also provide us with a competitive advantage. They are a key reason our customers view us as a trusted advisor, and we are an employer of choice for current employees and future talent.

Our Executive Leadership Team has challenged the Teradata Ethics & Compliance program to be among the best and most effective in the world. Teradata

managers and team leaders set the right tone and example when it comes to integrity, ethics, and compliance. We also hold individuals accountable to our high standards, and we take swift and decisive actions for compliance violations.

Integrity is also the top priority for the Teradata Board of Directors and senior leadership. Teradata Board members, officers, and senior executives—including me—are responsible under the same Code of Conduct as our employees, and we are held to the same high standards. The principles and values contained in the Code of Conduct guide our strategy and decisions. As leaders of the company, we are held to an even higher standard of accountability.

I know I can count on our Teradata team to maintain this high level of integrity in all their efforts. Our team’s past performance has enabled Teradata to achieve the “World’s Most Ethical Companies” award for many consecutive years. As we transform our company, I invite each of our team members and community of partners and suppliers to make a personal commitment to uphold the Code of Conduct in everything you do connected with Teradata. Use our Code of Conduct as a guide in making ethical decisions. Read it, understand how it applies to your job, and refer to it—often.

I know you will join me in ensuring Ethics and Compliance continues to be the foundation of who we are and what we do at Teradata.
