Definition:Advanced loss of profits insurance (ALOP)

🏭 Advanced loss of profits insurance (ALOP) provides financial protection to the owners or operators of construction and engineering projects against the loss of anticipated revenue or profit that results when project completion is delayed by physical damage covered under the project's underlying construction all risks or erection all risks policy. Known interchangeably in many markets as delay in start-up (DSU) insurance, ALOP occupies a distinct niche within engineering insurance, addressing the consequential financial losses that flow from construction-phase damage rather than the direct cost of repairing or replacing the damaged property itself.

🔧 Coverage triggers when an insured physical damage event — such as fire, storm, flood, machinery breakdown, or collapse — causes the project's operational start date to slip beyond the originally scheduled completion date. The policy indemnifies the project owner for the gross profit or net revenue that would have been earned during the delay period, subject to an agreed indemnity period and a time excess (the ALOP equivalent of a deductible, expressed in days or weeks rather than monetary terms). Increased costs reasonably incurred to reduce the delay — for instance, air-freighting replacement equipment rather than shipping it by sea — are also typically covered, provided they do not exceed the amount of loss they prevent. Perils must fall within the scope of the underlying material damage policy, which means delays attributable to design errors, contractual disputes, or supply chain disruptions unrelated to physical damage are excluded. Underwriters evaluating ALOP submissions require detailed construction schedules, critical path analyses, and financial projections to assess the exposure accurately.

🌍 ALOP insurance is a standard component of the project insurance package for major capital investments — power stations, petrochemical plants, toll roads, airports, and large commercial developments — across every major market. Project lenders and export credit agencies routinely require it as a condition of financing, recognizing that construction delays from physical damage events can threaten debt service schedules and project viability. Given the scale of sums insured, ALOP risks are frequently placed through specialized brokers in the London, Singapore, and Dubai engineering insurance markets, with significant participation from Lloyd's syndicates and international reinsurers. The growing exposure of infrastructure projects to climate-related perils — including extreme weather events and flooding — has heightened both demand for and scrutiny of ALOP coverage in recent years, making it a focal point for catastrophe modelers and underwriters alike.
