Definition:Advance loss of profit (ALOP) insurance

📋 Advance loss of profit (ALOP) insurance is a specialized form of business interruption coverage designed for project owners or investors who stand to lose anticipated income when a construction or infrastructure project is delayed by an insured peril. Sometimes called delay in start-up (DSU) insurance, ALOP attaches to a specific project rather than an ongoing business operation, covering the net profit and continuing fixed costs the insured would have earned had the project been completed on schedule.

⚙️ Coverage typically sits alongside a construction all-risk or erection all-risk policy. When physical damage—fire, storm, equipment failure—delays the project beyond its planned completion date, the ALOP policy responds after a pre-agreed time deductible (often expressed in days or weeks) has been exhausted. The indemnity period then runs until the project reaches the operational milestone defined in the policy, subject to a maximum period of indemnity. Underwriters evaluate the project's construction timeline, contractual penalties, projected revenue, and the quality of the contractor and project management team when pricing and structuring the cover.

💡 For lenders, equity investors, and project sponsors—particularly in energy, infrastructure, and large-scale real estate—ALOP insurance is a critical risk transfer tool because the financial exposure from delay can dwarf the cost of the physical damage that caused it. A six-month delay on a power plant, for instance, means six months of debt service with no revenue to offset it. Insurers and reinsurers active in engineering lines view ALOP as a complex but profitable class, requiring close collaboration between property underwriters, loss adjusters, and forensic accountants at the claims stage to quantify the actual financial impact of a delay.
