Definition:Premium bordereaux
📋 Premium bordereaux is a detailed report — typically prepared on a monthly or quarterly basis — that an MGA, coverholder, or broker submits to an insurer or reinsurer, listing individual premium transactions written, bound, or collected under a delegated authority arrangement or reinsurance treaty. Each line item in a premium bordereaux generally identifies the policyholder or risk, the policy number, inception and expiry dates, coverage details, and the premium amount — providing the carrier or reinsurer with granular visibility into the business being written on its behalf. The term "bordereaux" (from the French, meaning a detailed list or schedule) is deeply embedded in Lloyd's market practice and international reinsurance operations, though the concept exists under various names across global markets.
🔧 In practice, premium bordereaux serve as the primary data conduit between parties in a delegated authority relationship. Under a binding authority agreement at Lloyd's, for example, the coverholder is contractually required to submit bordereaux in a prescribed format — increasingly aligned with the Lloyd's Market Association's standards — enabling the managing agent and syndicate to monitor portfolio composition, verify that risks fall within agreed underwriting guidelines, and reconcile premium flows. Reinsurance bordereaux function similarly: under facultative and treaty arrangements, the ceding company provides the reinsurer with bordereaux detailing each ceded risk and premium allocation, enabling the reinsurer to perform its own actuarial analysis and reserving. The quality, timeliness, and accuracy of bordereaux data have historically been a pain point across the industry, with manual spreadsheet-based processes prone to errors, inconsistent formats, and significant reporting delays — sometimes stretching months beyond the period in question.
💡 Recognizing the cost of poor bordereaux management, the industry has invested heavily in standardization and automation. Initiatives led by ACORD, Lloyd's, and various insurtech platforms aim to digitize bordereaux workflows, enabling straight-through processing from the coverholder's or cedent's systems to the carrier's or reinsurer's data warehouse. Better bordereaux data unlocks faster claims validation, more accurate exposure accumulation tracking, and improved regulatory reporting under regimes like Solvency II that demand granular, timely data on risk exposures. For carriers relying on delegated authority for a growing share of their gross written premium, bordereaux management is not a back-office afterthought — it is a strategic capability that determines how effectively they can oversee far-flung distribution networks, detect underwriting drift, and manage aggregation risk across their portfolios.
