In plain words
A contractor wins one award to design, build and then operate a water treatment plant for ten years. The question is whether this is one obligation or several. Design and construction are usually combined, but operation and maintenance is usually a separate performance obligation. The price is split using standalone selling prices; construction revenue follows progress, and operation revenue follows the pattern of service delivery.
Why it matters
Bundled design-build-operate or EPC-plus-maintenance awards are routinely accounted for as a single blended performance obligation for administrative simplicity, but the construction and long-term operation/maintenance phases usually have fundamentally different risk profiles, margins and recognition patterns, collapsing them into one obligation smooths and mismatches margin recognition across two economically distinct services, misleading readers about which phase is actually driving profitability.
Diagnostic questions
Can the customer benefit from the design/construction output on its own or together with readily available resources, separately from the ongoing operation or maintenance service? Is the promise to operate or maintain the asset separately identifiable within the contract, or does it integrate so closely with the design-build work that it forms a single combined output? Are there separate pricing components, such as a lump-sum EPC price and a distinct per-year or per-unit O&M fee, that provide evidence of separate performance obligations? Have standalone selling prices been estimated for each distinct component using observable prices or an appropriate cost-plus-margin approach?
Recognition
- Identify all promised goods and services in the bundled award: design, construction, and operation/maintenance are candidates for separate performance obligations.
- Assess distinctness for each: is the good or service capable of being distinct (the customer can benefit from it on its own or with readily available resources), and is it distinct within the context of the contract (not highly interdependent or highly interrelated with other promises, and not providing a significant integration service)?
- Design and construction are typically not distinct from each other (construction integrates the design into a single output) but the operation/maintenance phase is usually distinct from construction, since it is a separable service capable of being (and often actually) provided independently by a different party.
- Allocate the transaction price to each distinct performance obligation based on relative standalone selling prices.
- Apply the appropriate recognition pattern to each: percentage-of-completion (over time, input or output method) for the design-build performance obligation; typically straight-line or another output measure (e.g. based on service level delivered) over time for the operation/maintenance performance obligation.
Measurement
Estimate standalone selling prices for the construction and operation/maintenance components using observable prices from separately sold contracts where available (e.g. the entity or competitors selling standalone O&M contracts), or an expected cost-plus-margin or adjusted market assessment approach where not directly observable. Measure progress on the construction performance obligation using cost-to-cost or another appropriate input/output method; measure the operation/maintenance obligation's revenue recognition pattern based on the actual pattern of service delivery, which is often but not always straight-line.
Presentation & disclosure
Disclose: (1) the identified performance obligations within the bundled arrangement and the basis for concluding they are (or are not) distinct; (2) the method and key assumptions used to estimate standalone selling prices, especially where not directly observable; (3) disaggregation of revenue between the construction/design phase and the operation/maintenance phase; (4) the transaction price allocated to remaining performance obligations and expected timing of recognition for the operation/maintenance component.
Common mistakes
- Treating the entire design-build-operate award as a single performance obligation purely because it is one legal contract with one combined price, without testing distinctness of the operation/maintenance service
- using a single blended progress measure across construction and multi-year operation, which mismatches cost and revenue timing between two economically different phases
- estimating the standalone selling price of the operation/maintenance component using an arbitrary percentage of total contract value rather than an evidence-based approach
- recognizing all construction margin upfront while deferring the entire combined price without any allocation to the distinct O&
- M obligation.
Simple example
A contractor is awarded a design-build-operate contract for a water treatment facility: SAR 200,000,000 total price, comprising design-build work and a 10-year O&M service. Design and construction are not distinct from each other (they form a single integrated output) but the O&M service is distinct, since similar O&M services are regularly sold separately in the market. Observable standalone selling prices: design-build SAR 150,000,000; 10-year O&M SAR 60,000,000 (total standalone SAR 210,000,000). Allocating the SAR 200,000,000 transaction price proportionally: design-build = 200,000,000 x (150,000,000/210,000,000) = SAR 142,857,000; O&M = 200,000,000 x (60,000,000/210,000,000) = SAR 57,143,000. At year-end, the design-build obligation is 40% complete (input method): Dr Cost of construction 25,000,000 Cr Cash / accounts payable 25,000,000 Dr Contract asset 57,143,000 Cr Revenue - design-build 57,143,000 (40% x 142,857,000 = 57,143,000) Once operations begin, O&M revenue of SAR 5,714,300 per year (57,143,000 / 10) is recognized on a straight-line basis reflecting the pattern of service delivery: Dr Contract asset / accounts receivable 5,714,300 Cr Revenue - operation and maintenance 5,714,300
Professional judgment
Whether the operation/maintenance service is 'distinct within the context of the contract' (not just capable of being distinct) requires assessing whether the entity provides a significant integration service that combines the design-build and O&M elements into a single combined output the customer could not achieve by contracting separately, for most infrastructure DBO/EPC-plus-maintenance awards this is not the case and the phases are distinct, but bespoke or highly interdependent operational requirements (e.g. where the operator must continuously reconfigure the asset based on real-time design feedback) could point the other way. Estimating standalone selling price for a long-term O&M service with no directly observable comparable market transaction (common for specialized infrastructure) is inherently estimation-heavy and should be based on a defensible cost-plus or adjusted market approach, documented and revisited if market benchmarks become available.
