In plain words
A master community includes roads, utilities and landscaping serving phases built over many years. The question is how to share this cost among units. The developer allocates the total expected infrastructure budget across all phases on a consistent basis, such as saleable area. When the budget changes, the new rate applies only to units not yet sold. Facilities the developer keeps, like a mall, stay out of unit cost.
Why it matters
Without systematic infrastructure cost allocation across all phases, early-phase handovers can show artificially inflated margins while later phases absorb a disproportionate share, distorting period-by-period profitability trends across what is often a decade-long master community program.
Diagnostic questions
Is there a master budget allocating total expected infrastructure and common-facility cost across all phases of the community, not just the current phase? What allocation base is used (saleable area or sales value), and is it applied consistently as units are costed and sold? Are developer-retained income-generating facilities (mall, clubhouse) carved out of the unit-cost allocation pool? When the total infrastructure budget or expected output changes, is the revised rate applied only prospectively to unsold/uncosted units, without restating margins already recognized?
Recognition
1) Build (and keep current) a master project budget that identifies total expected infrastructure and common-facility cost (roads, utilities, landscaping, community clubhouse, master signage) across the entire master-planned community, not just the current phase. 2) Select and document an allocation base, typically total saleable area or total expected sales value across all phases, and apply it consistently to allocate a share of the total infrastructure budget to each unit as it is costed and sold. 3) Separate out facilities the developer will retain and operate (e.g. a mall, a clubhouse run as an income-generating asset); these are the developer's own assets (PP&E or investment property) and should not be loaded into unit cost of sales. 4) When the total infrastructure budget or total expected sellable output changes materially (cost overruns, phase additions/removals, scope changes), true up the per-unit allocation rate prospectively, applying the revised rate to units not yet sold/costed rather than restating margins already recognized on earlier handovers. 5) Establish governance over the allocation model (periodic re-forecast, approval of revisions, audit trail) given the estimate spans many years and materially affects margin recognized on early-phase handovers.
Measurement
Measurement base: infrastructure and common facility costs directly attributable to preparing units for sale are capitalized into project inventory cost and allocated to units using a systematic basis (typically saleable area or relative sales value) applied consistently across all phases of the master community. Subsequent measurement: as the total cost or output estimate changes, recompute the per-unit rate and apply it prospectively to units not yet sold/costed (a change in accounting estimate, not a prior-period correction); allocated infrastructure cost embedded in unit cost is subsequently subject to the same lower-of-cost-and-NRV test as the rest of inventory.
Presentation & disclosure
Disclose the cost allocation methodology (basis used: area or value) and that it is applied on a total-project (multi-phase) basis; disclose significant changes in the total infrastructure cost estimate or total expected sellable output and their prospective effect on unit cost/margin; disclose facilities retained by the developer and excluded from unit cost allocation, and their classification (PP&E/investment property); disclose governance/review frequency over the master budget where relevant to estimate uncertainty disclosures under IAS 1.
Common mistakes
- Expensing infrastructure cost as incurred instead of capitalizing and allocating it across all phases, which understates early margins and overstates later ones
- charging the entire infrastructure budget to Phase 1 units only, dramatically overstating their cost and understating margins on later phases that also benefit from the same infrastructure
- failing to carve out developer-retained facilities (malls, clubs operated for income) from the unit-cost allocation pool
- restating margins already recognized on earlier handovers when the total budget or output estimate changes, instead of applying the revised rate prospectively
- using a stale allocation base (e.g. an outdated total saleable area) that no longer reflects approved masterplan changes.
Simple example
Scenario: A 6-phase Riyadh master community budgets total infrastructure cost of SAR 900,000,000 across a total expected 3,000,000 sqm of saleable area (SAR 300 per sqm allocation rate). A 200 sqm villa in Phase 1 therefore carries SAR 60,000 of infrastructure cost (200 x 300) in addition to its direct construction and land cost. As infrastructure spend is incurred (cumulative, funding the shared budget): Dr Development property inventory - Infrastructure cost pool 900,000,000 (over time, as incurred) / Cr Cash / Accounts payable 900,000,000 Allocating and releasing the villa's infrastructure share at handover (assume direct build+land cost SAR 940,000, total unit cost SAR 1,000,000 = 940,000 + 60,000 infrastructure share), sold for SAR 1,500,000: Dr Cash / Contract liability 1,500,000 / Cr Revenue 1,500,000 Dr Cost of sales 1,000,000 / Cr Development property inventory 1,000,000 If a later cost overrun raises the total infrastructure budget to SAR 1,050,000,000 (an increase of SAR 150,000,000) with 2,500,000 sqm of unsold/uncosted area remaining, the incremental SAR 150,000,000 is spread only over that remaining 2,500,000 sqm (SAR 60 per sqm), raising the prospective allocation rate for unsold output from SAR 300 to SAR 360 per sqm, applied only to units not yet sold/costed, without adjusting the SAR 60,000 already expensed on the Phase 1 villa above.
Professional judgment
The core estimate, total infrastructure cost and total expected sellable output over a decade-long masterplan, is inherently uncertain and evolves as phases are designed, sold and built, so the allocation rate is a moving target requiring periodic, disciplined re-forecast rather than a one-time calculation. Judgment is needed on which shared assets are genuinely infrastructure serving unit sales versus developer-retained income-generating assets, particularly for mixed-use elements like a clubhouse that may serve both purposes; an internally consistent, documented allocation policy is key evidence of appropriate judgment.
