Most PF/PFI models forecast 20 years or so ahead and indexation is an important part of the contractual process. Indexation is also the factor that can most affect a model since any change in rate now has a cumulative effect over time.

Macro-economic indexation is required to inflate real based inputs to nominal values in time. Indexation is based on ONS actual updates (possibly on a monthly basis) to bring the indexation up to date.

Independent and centralised indexation calculations are required in any model that looks to the future.
