Definition:Advance loss of profits insurance (ALOP)
🏗️ Advance loss of profits insurance (ALOP) — sometimes referred to as delay in start-up (DSU) insurance — protects project owners and financiers against the financial losses that arise when a construction or engineering project is delayed beyond its planned completion date due to physical damage covered under the underlying construction all-risks or erection all-risks policy. Rather than covering the cost of repairing the physical damage itself, ALOP addresses the downstream revenue shortfall: the profits the project was expected to generate during the period of delay, along with continuing fixed costs such as debt service, salaries, and contractual penalties that accumulate while the project stands incomplete.
⚙️ Coverage triggers only when the delay results from an insured peril under the project's primary construction policy — meaning the ALOP policy is inextricably linked to the material damage cover. If a fire destroys a partially completed manufacturing plant and reconstruction takes an additional eight months, the ALOP policy responds to the lost revenue and standing charges during that extended period, subject to a time excess (waiting period) and an outer indemnity period limit. Underwriting ALOP requires granular analysis of the project timeline, critical path methodology, projected revenue ramp-up curves, and the financial model underpinning the venture. Insurers in major construction and engineering markets — London, Singapore, the Middle East, and increasingly Latin America — typically write ALOP as a section within the broader construction policy or as a standalone companion policy. Reinsurers take a keen interest in ALOP exposures because large infrastructure projects can generate claims running into hundreds of millions of dollars, especially when delays cascade through complex supply chains.
📊 The value of ALOP cover has grown in step with the scale and complexity of modern infrastructure investment, from liquefied natural gas terminals to renewable energy installations and semiconductor fabrication plants. Project lenders and project finance banks routinely require ALOP insurance as a condition of financing, since debt service obligations do not pause when construction stalls. For brokers advising on major projects, structuring the ALOP section demands close collaboration with the project's financial advisors to ensure the indemnity period, sum insured, and time excess align with realistic worst-case delay scenarios. Mispricing or underinsuring this exposure can leave a project sponsor facing a solvency-threatening gap between the date revenue was expected to begin and the date it actually does.
