Businesses embed our solutions into their process workflows to acquire new customers, assess consumer ability to pay for services, identify cross-selling opportunities, measure and manage debt portfolio risk, collect debt, verify consumer identities and investigate potential fraud. Consumers use our solutions to view their credit profiles and access analytical tools that help them understand and manage their personal information and take precautions against identity theft.

Our deep analytics resources, including our people and tools driving predictive modeling and scoring, customer segmentation, benchmarking and forecasting, enable us to provide businesses and consumers with better insights into their data. Our decisioning capabilities, which are generally delivered on a software-as-a-service platform, allow businesses to interpret data and apply their specific qualifying criteria to make decisions and take actions. Collectively, our data, analytics and decisioning capabilities allow businesses to authenticate the identity of consumers, effectively determine the most relevant products for consumers, retain and cross-sell to existing consumers, identify and acquire new consumers and reduce loss from fraud and data breaches. Similarly, our capabilities allow consumers to see how their credit profiles have changed over time, understand the impact of financial decisions on their credit scores, manage their personal information and take precautions against identity theft.</span></div>

A performance obligation is a promise in a contract to transfer a distinct good or service to a customer.

Our Other Performance Obligations include the sale of certain batch data sets and various professional and other services. See Note 14, “Revenue,” for a further discussion about our revenue recognition policies.</span></div>Deferred revenue generally consists of amounts billed in excess of revenue recognized for the sale of data services, subscriptions and set up fees. As our contracts with customers generally have a duration of one year or less, our contract liabilities consist of deferred revenue that is primarily short-term in nature. The current and long-term portions of deferred revenue are included in other current liabilities and other liabilities.

These actions generally assert claims for violations of federal or state credit reporting, consumer protection or privacy laws, or common law claims related to privacy, libel, slander or the unfair treatment of consumers, and may include claims for substantial or indeterminate compensatory or punitive damages, or injunctive relief, and may seek business practice changes. We believe that most of these claims are either without merit or we have valid defenses to the claims, and we vigorously defend these matters or seek non-monetary or small monetary settlements, if possible. However, due to the uncertainties inherent in litigation, we cannot predict the outcome of each claim in each instance.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In the ordinary course of business, we also are subject to governmental and regulatory examinations, information-gathering requests, investigations and proceedings (both formal and informal), certain of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. In connection with formal and informal inquiries by these regulators, we routinely receive requests, subpoenas and orders seeking documents, testimony, and other information in connection with various aspects of our activities.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In view of the inherent unpredictability of litigation and regulatory matters, particularly where the damages sought are substantial or indeterminate or when the proceedings or investigations are in the early stages, we cannot determine with any degree of certainty the timing or ultimate resolution of litigation and regulatory matters or the eventual loss, fines, penalties or business impact, if any, that may result. We establish reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated. The actual costs of resolving litigation and regulatory matters, however, may </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">be substantially higher than the amounts reserved for those matters, and an adverse outcome in certain of these matters could have a material adverse effect on our consolidated financial statements in particular quarterly or annual periods.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On a regular basis, we accrue reserves for litigation and regulatory matters based on our historical experience and our ability to reasonably estimate and ascertain the probability of any liability. However, for certain of the matters described below, we are not able to reasonably estimate our exposure because damages have not been specified and (i) the proceedings are in early stages, (ii) there is uncertainty as to the likelihood of a class being certified or the ultimate size of the class, (iii) there is uncertainty as to the outcome of similar matters pending against our competitors, (iv) there are significant factual issues to be resolved, and/or (v) there are legal issues of a first impression being presented. However, for these matters we do not believe based on currently available information that the outcomes will have a material adverse effect on our financial condition, though the outcomes could be material to our operating results for any particular period.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">To reduce our exposure to an unexpected significant monetary award resulting from an adverse judicial decision, we maintain insurance that we believe is appropriate and adequate based on our historical experience. We regularly advise our insurance carriers of the claims (threatened or pending) against us in the course of litigation and generally receive a reservation of rights letter from the carriers when such claims exceed applicable deductibles. We are not aware of any significant monetary claim that has been asserted against us in the course of pending litigation that would not have some level of coverage by insurance after the relevant deductible, if any, is met.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As of </span><span style="font-family:inherit;font-size:10pt;">December 31, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">2018</span><span style="font-family:inherit;font-size:10pt;">, we accrued </span><span style="font-family:inherit;font-size:10pt;"><span>$30.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$33.2 million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, for anticipated claims. These amounts were recorded in other accrued liabilities in the consolidated balance sheets and the associated expenses were recorded in selling, general and administrative expenses in the consolidated statements of income. Legal fees incurred in connection with ongoing litigation are considered period costs and are expensed as incurred.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">OFAC Alert Service</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As a result of a decision by the United States Third Circuit Court of Appeals (</span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Cortez v. Trans Union LLC</span><span style="font-family:inherit;font-size:10pt;">) in 2010, we modified one of our add-on services we offer to our business customers that was designed to alert our customer that the consumer, who was seeking to establish a business relationship with the customer, may potentially be on the Office of Foreign Assets Control, Specifically Designated National and Blocked Persons alert list (the “OFAC Alert”). The OFAC Alert service is meant to assist our customers with their compliance obligations in connection with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT) Act of 2001.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez v. Trans Union LLC</span><span style="font-family:inherit;font-size:10pt;">, (No. 3:12-cv-00632-JSC, United States District Court for the Northern District of California), filed in 2012, the plaintiff has alleged that: the OFAC Alert service does not comply with the </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Cortez</span><span style="font-family:inherit;font-size:10pt;"> ruling; we have willfully violated the Fair Credit Reporting Act (“FCRA”) and the corresponding California state-FCRA based on the </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Cortez</span><span style="font-family:inherit;font-size:10pt;"> ruling by continuing to offer the OFAC Alert service; and there are one or more classes of individuals who should be entitled to statutory damages (i.e., </span><span style="font-family:inherit;font-size:10pt;"><span>$100</span></span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;"><span>$5,000</span></span><span style="font-family:inherit;font-size:10pt;"> per person) based on the allegedly willful violations. In July 2014, the Court in </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez</span><span style="font-family:inherit;font-size:10pt;"> certified a class of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>8,000</span></span><span style="font-family:inherit;font-size:10pt;"> individuals solely for purposes of statutory damages if TransUnion is ultimately found to have willfully violated the FCRA, and a sub-class of California residents solely for purposes of injunctive relief under the California Consumer Credit Reporting Agencies Act. While the Court noted that the plaintiff is not seeking any actual monetary damage, the class certification order was predicated on a disputed question of Ninth Circuit law (currently there is a conflict between the federal circuits) that was awaiting action by the United States Supreme Court. Our motion to stay the </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez</span><span style="font-family:inherit;font-size:10pt;"> proceeding was granted and the proceeding stayed pending action by the U.S. Supreme Court in </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Spokeo v. Robins</span><span style="font-family:inherit;font-size:10pt;">. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On May 16, 2016, the U.S. Supreme Court issued its decision in </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Spokeo v. Robins</span><span style="font-family:inherit;font-size:10pt;">, holding that the injury-in-fact requirement for standing under Article III of the United States Constitution requires a plaintiff to allege an injury that is both “concrete and particularized.” The Court held that the Ninth Circuit’s analysis failed to consider concreteness in its analysis and vacated the decision and remanded to the Ninth Circuit to consider both aspects of the injury-in-fact requirement. Following the U.S. Supreme Court’s decision, the stay in the </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez</span><span style="font-family:inherit;font-size:10pt;"> matter was lifted. In October 2016, the Court in </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez</span><span style="font-family:inherit;font-size:10pt;"> denied our motion to decertify the classes based on the implications of </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Spokeo</span><span style="font-family:inherit;font-size:10pt;">. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On June 21, 2017, the jury in </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez</span><span style="font-family:inherit;font-size:10pt;"> returned a verdict in favor of a class of </span><span style="font-family:inherit;font-size:10pt;"><span>8,185</span></span><span style="font-family:inherit;font-size:10pt;"> individuals in the amount of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>$8.1 million</span></span><span style="font-family:inherit;font-size:10pt;"> (</span><span style="font-family:inherit;font-size:10pt;"><span>$984.22</span></span><span style="font-family:inherit;font-size:10pt;"> per class member) in statutory damages and approximately </span><span style="font-family:inherit;font-size:10pt;"><span>$52.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> (</span><span style="font-family:inherit;font-size:10pt;"><span>$6,353.08</span></span><span style="font-family:inherit;font-size:10pt;"> per class member) in punitive damages. In November 2017, the trial court denied our post-trial motions for judgment as a matter of law, a new trial and a reduction on the jury verdict. We appealed the </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ramirez</span><span style="font-family:inherit;font-size:10pt;"> ruling to the United States Court of Appeals for the Ninth Circuit and posted a bond at nominal cost to stay the execution of the judgment pending resolution of our appeal. The Court heard oral arguments on February 14, 2019, and could render its decision at any time.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The timing and outcome of the ultimate resolution of this matter is uncertain. Despite the jury verdict, we continue to believe that we have not willfully violated any law and have meritorious grounds for seeking modification of the judgment on appeal. Given the complexity and uncertainties associated with the outcome of the current and any subsequent appeals, there is a wide range of potential results, from vacating the jury verdict in its entirety to upholding some or all aspects of the verdict. As of December 31, </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">2019, we have accrued a liability for this matter equal to our current estimate of probable losses (the amount of the verdict for statutory damages) and our costs of defending this matter, and a corresponding and fully-offsetting receivable representing the amounts we expect to receive from our insurance carriers. The accrued liability does not include any amount for the punitive damages awarded by the jury since it is not probable, based on legal precedent, that the amount of the punitive damages awarded by the jury will survive our post-judgment actions. We currently estimate, however, that the reasonably possible loss in future periods for punitive damages falls within a range from </span><span style="font-family:inherit;font-size:10pt;"><span>zero</span></span><span style="font-family:inherit;font-size:10pt;"> to something less than the amount of the statutory damages awarded by the jury. This estimate is based on currently available information. As available information changes, our estimates may change as well. The extent of our insurance coverage for punitive damages in this matter is uncertain and may be less than all of such punitive damages ultimately awarded. In the event all or a portion of the punitive damages award survives our post-judgment actions, we will continue to engage with our insurance carriers and aggressively pursue all potential recoveries.</span></div>
