Putting Our Business Principles into Action

TransUnion

Code of

Business Conduct

September 2012

LOGO

Message from the President and CEO

A work environment that fosters trust, respect, and openness of communication is one way that TransUnion will continue to be a great place to work around the globe.

We expect our associates to be committed to ethical and law-abiding conduct. Our continued success depends on your ongoing commitment to meeting these expectations every day.

This Code of Business Conduct describes many of the behaviors associated with acting in accordance with our principles. Although the Code covers a wide range of situations, it is impossible to anticipate every possible question or issue that you may encounter on a daily basis. If you have questions or need further guidance, you should go to your manager or contact one of the Code Officers. If you want your question to remain anonymous, you should use the TransUnion Hot Line.

Each year all of us will be asked to re-commit to TransUnion’s business principles. We all must take these responsibilities seriously so that together we can achieve even greater success in the future.

Thank you for your continuing support, dedication, and contributions to TransUnion.

Those who invest in our businesses

The communities where we operate

Core Business Principle #1: Ethics and Values

To conduct our business with honesty, integrity, and trust.

To respect human rights.

To protect personal information entrusted to us.

To obey the law and operate with the highest ethical standards.

To seek partners, suppliers, vendors, and customers with the same ethics and values.

To take responsibility for our mistakes.

You are expected to:

LOGO

Core Business Principle #1: Ethics and Values

If you are a manager, you are a role model to everyone who supports or does business with TransUnion.

A manager is responsible for:

• Confirming that your staff reads and understands all TransUnion Policies;

• Answering associates’ questions about TransUnion Policies and, when in doubt about the right course of action, seeking advice and guidance from the TransUnion Law Department or Compliance Department;

• Never condoning any conduct or activity that may raise questions about TransUnion’s honesty, integrity, or compliance with Legal Standards;

• Promoting a culture of ethical business conduct;

• Encouraging everyone in our organization to raise concerns when they come up;

• Reporting all violations of this Code that you are aware of to a Code Officer; and

• Implementing with Human Resources and a Code Officer appropriate disciplinary procedures after a Code violation occurs.

Our Legal Standards require that you conduct business in full compliance with the letter and spirit of all laws, rules, regulations and court orders that apply to TransUnion. These Legal Standards may be reflected in TransUnion Policies, in information described to you by your manager or in information discussed with you by our Law Department or Compliance Department.

TransUnion Policies include this Code of Business Conduct as well as the various policies, procedures and standards that have been adopted at the enterprise and business unit levels.

Did You Know?

The Directors of TransUnion Corp. periodically review our Code of Business Conduct. This includes confirming that our managers are providing the appropriate “tone at the top” to encourage compliance with this Code, TransUnion Policies, and Legal Standards.

LOGO

Core Business Principle #1: Ethics and Values

Bribes, Inducements, Kickbacks, and Payoffs

When acting for or on behalf of TransUnion, you must not:

• Make, promise, offer or deliver any donation, gift, favor, payment, contribution or other gratuity, to an official or employee of any U.S. or foreign government or governmental agency, or any person seeking a public office; or

• Make any indirect payments to organizations associated with such employee, official, or person. For example you cannot make indirect payments through attorney’s fees, sales commissions, political committees or parties, or consultant’s fees.

You are permitted to make payments that are legally required such as fees for licenses, permits, or other official documents required to do business. However prior to authorizing any such payment, you should confirm with your manager that the payment has been approved by the TransUnion Law Department.

Gifts, Entertainment and Meals

You may give or accept gifts or entertainment from or to customers or vendors only if they are ordinary, reasonable and of limited value. Such gifts or entertainment must not violate any Legal Standards or generally accepted ethical standards including the standards of the recipient’s organization.

You may be a guest or host for customary business functions, such as meals, provided they are for a valid business purpose and reasonable in cost.

You may support your selected political parties or candidates for public office with your own funds as long as you do not imply that your action reflects the opinion of TransUnion or is on behalf of TransUnion.

You may not make a political contribution with TransUnion’s funds or request reimbursement from TransUnion for a political contribution unless your manager has approved the contribution and received prior approval from the TransUnion Law Department.

Core Business Principle #1: Ethics and Values

Conflict of Interest and Business Opportunities

What is a conflict of interest?

It occurs when you or your family or friends benefit from a business opportunity that is being or may be pursued by TransUnion. If you expect to receive some type of benefit from a transaction that TransUnion participates in (other than a benefit that you receive directly from TransUnion and it is clearly known to TransUnion) you have a conflict of interest.

Because it impairs your ability to make objective judgments, any conflict of interest, or even something that appears to be a conflict of interest, should always be avoided. However if the conflict cannot be avoided, you must disclose it and have it approved by your manager or a Code Officer and the TransUnion Human Resources Department.

In no event should you take advantage of any business opportunity that you learn about through your duties with TransUnion.

In particular you should not:

• Use TransUnion’s property, information, or your position for personal gain. An example is entering into any investment or business opportunity for yourself, your family or friends, or any business that is controlled by you, your family, or friends, which you know about through your job at TransUnion.

• Compete with TransUnion directly or indirectly for business opportunities unless you have disclosed the opportunity to your manager and to the TransUnion Law Department. You also must have been specifically advised that TransUnion will not pursue that particular opportunity.

• Attempt to obtain an improper personal benefit from TransUnion, such as an improper loan.

Your use must also be in compliance with applicable TransUnion Policies and Legal Standards. Assets, including data in the possession of TransUnion, must never be used, removed, transferred or borrowed unless your manager has approved it and it is compliant with TransUnion Policies.

Your use of TransUnion’s computer systems is at the sole discretion of TransUnion. You should secure and protect all computers and tele-communications equipment like cell phones, wireless email devices, and laptops assigned to you.

You are required to keep all passwords associated with that equipment and our computer systems confidential at all times.

Compliance With Our Code of Business Conduct

Compliance with this Code of Business Conduct is not an option. It must be followed by all who represent TransUnion throughout the world.

Tips and Guidelines

When faced with a situation where you have a concern, keep these steps in mind:

1. Make sure you have all the facts. You must be fully informed to reach the right answer.

2. Understand exactly what you are being asked to do. Does it seem right or unethical or improper? Use your judgment and common sense.

3. Clarify your responsibility and role. Are your co-workers and colleagues informed? Is there shared responsibility? It may help to get others involved and discuss the problem.

4. Discuss the problem with your manager. This is basic for all situations. It is your manager’s responsibility to help solve problems. If for some reason your manager is not helpful, you should contact a Code Officer or the TransUnion Hot Line.

5. Seek help from other TransUnion resources. If you feel you cannot discuss the matter with your manager, you should discuss it with your Human Resources representative, a Code Officer or someone from TransUnion’s Compliance Department or Law Department. They will make sure that you obtain the guidance you need. Ignoring the issue is not an acceptable option.

6. Always ask first, act later. If you are unsure of what to do in any situation, seek help and guidance before you act.

You may ask questions about, or report suspected violations of our Code of Business Conduct in confidence and without fear of retaliation. Your anonymity will be protected to the fullest extent possible if you contact the TransUnion Hot Line or a Code Officer.

TransUnion will not permit retaliation of any kind against you for asking questions or reporting, in good faith, possible violations of this Code of Business Conduct.
