Audited planning profile
This conservative five-year profile applies a 1.2× editable baseline across 60 model periods to the passport renewal buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Use this profile when protecting downside matters more than optimizing the headline result. Treat maintenance, replacement and compounding assumptions as material over five years.
Public holidays, legal notice periods, calendar conventions, time-zone cutoffs and eligibility rules are not inferred unless entered.
Confirm the governing time zone, official calendar and any contractual or legal deadline.
