Paying for readiness, not usage
Social infrastructure — schools, clinics, courts, staff housing — produces a service rather than a revenue stream. The availability structure responds to that: the public authority pays a periodic amount for the asset being available to an agreed standard, with deductions when it is not.
Demand risk sits with the authority. The private party carries construction, availability, and lifecycle cost. That allocation is well understood and is why these projects attract long-tenor debt in markets where merchant risk would not.
Where the diligence concentrates
The deduction regime. This is the operative commercial term. How availability is measured, what unavailability costs, whether deductions are capped, and how quickly a remedied fault stops the meter — these determine the volatility of the revenue a lender is underwriting. A regime with uncapped deductions and short cure periods is not bankable at the leverage sponsors usually assume.
The payment covenant. In the Gulf the authority is typically a ministry or a government entity funded by annual appropriation. Lenders ask what stands behind the obligation across a twenty-five year term that outlasts any budget cycle: an explicit undertaking, a standing appropriation mechanism, or practice.
Lifecycle obligations. The private party is usually responsible for maintaining the asset to handover standard. Lifecycle cost assumptions are a frequent source of dispute late in a concession, and lenders test reserves against them rather than accepting the sponsor's schedule.
Handback. What condition the asset must be in at expiry, who inspects, and what happens if it falls short. Handback reserves accrue for years and are negotiated in the first month.
What is specific to the region
Gulf availability projects usually sit inside a broader national programme with a delivery timetable of its own. That creates pressure to compress procurement, which lenders notice: a shortened bid period with unresolved risk allocation produces conditional bids and reopened terms after preferred bidder selection.
The second regional feature is the mix of financing. Where an availability project carries a Shariah-compliant tranche, the deduction regime has to be expressed in a way that works for both structures, since the Islamic tranche's return cannot simply track a deduction mechanism designed for conventional debt service.
What to settle first
- The deduction regime, with caps and cure periods modelled against realistic operating performance
- What stands behind the payment obligation beyond the current budget cycle
- Lifecycle assumptions tested independently, with reserves sized to them
- Handback standard and inspection process, agreed at financial close
- If the financing is mixed, how deductions translate across both tranches
Availability structures work. They fail when the deduction regime is agreed as a technical schedule rather than as the revenue term it actually is.
