Personal credit rating is done so results are accurate, the system fair and the process open and transparent; favourable as well as adverse information is considered; there is no unreasonable discrimination by sex, region of origin or nationality and no unreasonable weighting of particular items when building models; and specialised personal credit rating companies do not engage in unfair practices such as raising the scores of customers of affiliates (Articles 22-3(1) and 22-4).
