'Contract termination' has been changed to 'Managed termination' because the latter implies early termination of an agreement e.g. through default, as opposed to a contract being wound-up at the end of an agreed concession period. A new sub-category, 'Voluntary termination', has been developed due to the possibility that a consortium partner may wish to withdraw its services because of financial distress or other reasons.
No new treatments or integrating arguments are identified for service provider failure or voluntary termination.
