The provision for Civil and others represents the present value of the directors’ best estimate of the future outflow of economic benefits that will be required under the Group’s obligations for the final settlement cost of complaints and litigations derived from tax claims and damages. All the claims provisioned under tax or damages, respectively, are of a similar nature and are not individually material.
