In September 2015, Experian North America suffered an unauthorised intrusion to its Decision Analytics computing environment that allowed unauthorised acquisition of certain data belonging to a client, T-Mobile USA, Inc. We notified the individuals who may have been affected and offered free credit monitoring and identity theft resolution services. In addition, government agencies were notified as required by law.
We have one remaining claim in respect of the incident and are working with the government bodies involved in this remaining claim. It is currently difficult to predict the result, including the timing and scale, but we do not believe the outcome will be material to the Group. In the event of an unfavourable outcome, the Group may benefit from applicable insurance recoveries.
