  +In more detail:
   
   * `initialReevaluationInterval` is set to 10 (if no payment is posted, the overdue state is recomputed 10 days later to match `timeSinceEarliestUnpaidInvoiceEqualsOrExceeds`)
   * `WARNING`:
  
positive.code: * `CANCELLATION`:
  ** `subscriptionCancellationPolicy` is set to `END_OF_TERM` to indicate that subscriptions should be cancelled in such a way that we do not generate credit for the account (no proration)
  
  
  **Beware** The definition order of the states in the XML configuration file is important: You must have the first state at the bottom and then all the way up to the last state (as shown in our example).
  
  This XML file can be specified as a property in the Kill Bill configuration file as follows:
  [source,bash]
  
negative.code: 
  === Overdue configuration
  
  Next, you need to define the overdue configuration XML file. 
  
  ==== Creating Overdue.xml file
  
  Based on the scenario defined above, the overdue configuration will define the three states the account will go through:
  
  1. The account will enter the `WARNING` state 10 days after the first unpaid invoice (Trial period will last for 10 days, after which a $10 invoice will be generated. 10 days after this (20 days after the subscription creation), the account needs to enter the `WARNING` state)
  2. 4 days later, the account will move to the `BLOCKED` state
