Definition:Bordereaux: Difference between revisions

📊 '''Bordereaux''' is a detailed report — typically delivered as a structured data file — that a [[Definition:Coverholder | coverholder]], [[Definition:Managing general agent (MGA) | managing general agent]], or [[Definition:Ceding company | ceding company]] submits to an [[Definition:Insurance carrier | insurer]] or [[Definition:Reinsurer | reinsurer]], listing individual policy, [[Definition:Premium | premium]], or [[Definition:Claims management | claims]] transactions over a defined period. The term originates from French and is used as both singular and plural in insurance practice. There are two primary types: a premium bordereau, which records every policy bound along with its key attributes such as insured name, [[Definition:Coverage limit | coverage limits]], premium, effective dates, and [[Definition:Class of business | class of business]]; and a claims or loss bordereau, which itemizes individual claims, [[Definition:Reserve (insurance) | reserves]], and payments.

🔄 Bordereaux are usually exchanged on a monthly or quarterly cycle, depending on the terms of the [[Definition:Binding authority agreement | binding authority agreement]]. The coverholder extracts the data from its [[Definition:Policy administration system | policy-administration]] or [[Definition:Claims management system | claims-management system]] and transmits it in a format agreed upon with the carrier — historically spreadsheets, but increasingly via [[Definition:Application programming interface (API) | API]] integrations or standardized data platforms. Upon receipt, the carrier's operations team ingests the data into its own systems for premium booking, reserve posting, [[Definition:Regulatory reporting | regulatory reporting]], and [[Definition:Actuarial analysis | actuarial analysis]]. Data-quality checks are run to flag anomalies such as missing fields, policies written outside the agreed [[Definition:Underwriting guideline | guidelines]], or unusual premium patterns.

🎯 Accurate, timely bordereaux reporting is the backbone of effective [[Definition:Delegated underwriting authority (DUA) | delegated-authority]] oversight. Without reliable transaction-level data, a [[Definition:Capacity provider | capacity provider]] is essentially flying blind — unable to monitor portfolio [[Definition:Aggregation risk | aggregation]], validate that underwriting guidelines are being followed, or set appropriate reserves. Industry initiatives to standardize bordereaux formats and move toward real-time data sharing are among the most consequential infrastructure projects in the [[Definition:London market | London]] and global [[Definition:Specialty insurance | specialty]] markets, promising to compress reporting lags and transform how carriers manage their delegated books.
