The question "Who is best placed to reduce the probability of the event occurring?" should be asked for every aspect of the transaction and should go beyond the headline event. For example, it is likely that the private-sector party is best placed to take the responsibility for the design and construction of any new infrastructure. However, if the infrastructure is being renovated or upgraded, it may be that the public sector is better placed to take the responsibility for the condition of the existing infrastructure, unless the public-sector parties are able to provide extensive information or allow surveys that can be used to establish its current condition.
