  9. 9. Credit Scoring Typology Application Score - Application scores are a type of credit score used by banks and finance houses to decide which applicants are to be taken on, based purely on the information given in the credit application form. This scoring is heavily used during the acquisition period of a credit life cycle. Bureau Score - A Bureau Score is a credit score which is calculated only based on the information from a detailed credit report. Sometimes there is a mixture of private and public credit reports used to obtain the „bureau score“. This scoring is heavily used during acquisition, monitoring and collection periods of a credit life cycle. Behavioural Score – This is limited to existing client portfolio of a bank or a finance house. This score allows lenders to make better decisions in managing existing clients by forecasting their future performance. This score is heavily used for credit limit renewal, credit limit increase, up-selling, cross-selling and also for the soft collection period of a credit life cycle.Page 9

  12. 12. Concerns over Credit Scoring Influence on the Credit Granting Process Credit scoring may have adverse effects on certain populations, particularly minorities Credit scoring is not loss prevention panacea and it is neccessary to keep that in mind during credit lending process definition and design Some factors used to estimate credit scores may have an adverse effect on certain groups Automated technologies may disadvantage individuals with nontraditional credit experiences Judgmental evaluations may be better able to detect errors or inaccuracies With lending and retailing becoming more automated, risky consumers will face growing disadvantages and this may lead to some acting in the name of social justicePage 12
  13. 13. Conclusion The Credit Lending Industry is an area, where RISK is the norm rather than the exception It is necessary to adopt many measures which may help to reduce exposure to high risk Those who would like to win the market battle have to find a balance between risk and return on assets Credit scoring is a pragmatic and widely proven method of risk identification and quantification The statistical credit scoring model is much more powerful than a judgmental opinion and decision The use of credit scoring during loan providing and monitoring is an essential feature of a modern bank and its implementation costs are quickly recovered Companies that are confident in their models, will start cherry picking and can target the most profitable customers.Page 13
