       Problem Statement
• Credit Customers are obliged to make regular
  (usually) monthly payments to repay their lending
  facilities                                                   Increasing delinquency – Missed Payments
• Customers are categorised as sitting in a range of
  buckets, representing the number of missed
  payments
• If a payment is missed or not made customers will
  ‘roll’ to the next delinquency bucket
• If a payment is made the customer will ‘roll back’ the   U
  number of buckets the payments represents                T   X                     60          90
                                                                         30                               Losses
• At 90 days past due the customer is deemed to have       D
  ‘defaulted’, and a loss may be incurred
• NPLs occur at 90 days past due, Banks will aim to
  avoid a 90-day status
                                                                   Recovery – Making Payments
What is Collections Scoring?
   • Collections Scoring targets accounts that are delinquent with the aim
     to control the roll rate from bucket to bucket
   • Outcomes are used to prioritise the order in which customers are
     contacted when delinquent
      • Calling Strategies
      • Letter Strategies
   • Recovery or Payment Projection Models aim to predict the amount of
     collected post default
      • Early Debt Sale
      • Recoveries Strategies
      • Input into Loss Given Default (LGD)
