Definition:Scratch
📋 Scratch is a term used in insurance and reinsurance markets to describe the breakeven point on an account, treaty, or book of business — the threshold at which premiums collected exactly equal losses and expenses incurred, producing neither profit nor deficit. When an underwriter or reinsurer says a program "scratched," they mean it returned to zero — no money was made, but none was lost either. The concept is particularly common in Lloyd's market vernacular and in treaty reinsurance negotiations, where participants evaluate historical performance relative to scratch to judge whether a relationship or portfolio merits continued support.
⚙️ Determining whether a book has scratched requires aggregating all premiums earned against all incurred losses (both paid and reserved) plus allocated expenses, such as brokerage, acquisition costs, and administrative overhead. In reinsurance, the calculation often involves tracking the development of loss ratios over multiple years, since long-tail lines like casualty and professional liability may not reveal their true outcome for a decade or more. A treaty that appears profitable in its early years can deteriorate past scratch as late-reported claims emerge, making the concept dynamic rather than static. Underwriters use scratch as a reference point in pricing discussions — a proposed rate might be described as "above scratch" or "below scratch" to signal whether it is expected to generate an underwriting profit or merely cover costs.
💡 While scratching might sound like a neutral outcome, it is generally viewed unfavorably by insurers and reinsurers because it means capital was deployed and risk was borne with no return. Investors and capital providers expect compensation for assuming insurance risk, so consistently scratching on a portfolio indicates that pricing is inadequate relative to the volatility involved. In performance reviews and renewal negotiations, accounts that have historically hovered around scratch may face pressure for rate increases, restructured terms, or non-renewal. For MGAs and coverholders reporting results to their capacity providers, demonstrating that a book comfortably exceeds scratch — after accounting for catastrophe loads and trend — is essential to maintaining binding authority relationships.
