🏗️ '''Advance loss of profits (ALOP) insurance''' — also known as delay in start-up (DSU) insurance in many markets — is a specialized form of [[Definition:Business interruption insurance | business interruption]] coverage designed for projects under construction, protecting the project owner or investor against the financial loss that results when a construction project is delayed beyond its planned completion date due to physical damage covered under the related [[Definition:Construction insurance | construction all-risks (CAR)]] or [[Definition:Erection all-risks insurance | erection all-risks (EAR)]] policy. Unlike standard [[Definition:Business interruption insurance | business interruption insurance]], which covers lost income from an already-operating business, ALOP/DSU responds to income that would have been earned had the project commenced operations on time — making it inherently forward-looking and reliant on projected financial performance rather than historical earnings.

⚙️ Coverage is typically structured as an extension or companion policy to the underlying [[Definition:Construction insurance | CAR]] or [[Definition:Erection all-risks insurance | EAR]] policy, meaning the ALOP coverage is triggered only when a physical loss or damage event covered by the construction policy causes a delay that pushes the project's operational start date beyond an agreed target. The policy responds by indemnifying the insured for lost gross profit, fixed costs that continue during the delay, and increased cost of working — subject to a time [[Definition:Deductible | deductible]] (waiting period) and a maximum [[Definition:Indemnity period | indemnity period]] that caps the insurer's exposure. [[Definition:Underwriting | Underwriting]] ALOP requires careful assessment of the project timeline, the financial projections underpinning expected revenue, the construction methodology, supply chain dependencies, and the likelihood that physical damage events could create meaningful delays. The coverage is common in large infrastructure, energy, petrochemical, and power generation projects globally, where delays of even a few weeks can translate into tens of millions of dollars in lost revenue.

💡 Project lenders and investors frequently require ALOP/DSU coverage as a condition of financing, because a significant construction delay can imperil the borrower's ability to service debt from projected cash flows. This makes the product a critical component of the overall [[Definition:Project insurance | project insurance]] program alongside [[Definition:Construction insurance | CAR/EAR]], [[Definition:Third-party liability insurance | third-party liability]], and [[Definition:Professional indemnity insurance | professional indemnity]] coverages. Pricing is complex and highly bespoke, reflecting the unique risk profile of each project; [[Definition:Reinsurance | reinsurers]] play an important role in absorbing the large potential exposures, particularly for megaprojects. Markets with strong ALOP expertise include [[Definition:Lloyd's of London | Lloyd's of London]], the Singapore specialty market, and major Continental European [[Definition:Insurance carrier | carriers]] with engineering insurance divisions. As global construction activity continues to grow — driven by energy transition infrastructure, data centers, and urbanization — ALOP/DSU insurance remains a vital tool for managing the financial consequences of the unexpected in some of the world's most capital-intensive undertakings.
