<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📉 &#039;&#039;&#039;Gross loss ratio&#039;&#039;&#039; is the proportion of an [[Definition:Insurance carrier | insurer&#039;s]] [[Definition:Gross written premium (GWP) | gross written premium]] consumed by [[Definition:Incurred loss | incurred losses]] and [[Definition:Loss adjustment expense (LAE) | loss adjustment expenses]] before any recoveries from [[Definition:Reinsurance | reinsurance]]. By stripping out the cushioning effect of [[Definition:Ceded premium | ceded]] arrangements, the metric exposes the fundamental [[Definition:Underwriting | underwriting]] quality of the risks a carrier has accepted — making it one of the purest indicators of how well a book of business is actually performing.<br /> <br /> 🔍 To arrive at the figure, analysts divide gross incurred losses (including [[Definition:Case reserve | case reserves]] and [[Definition:Incurred but not reported (IBNR) | IBNR]] estimates) by gross written or [[Definition:Gross earned premium | gross earned premium]] for the same period and express the result as a percentage. A property insurer that earns $400 million in gross premium and records $280 million in gross losses posts a 70 percent gross loss ratio. The calculation can be performed at the enterprise level, by [[Definition:Line of business | line of business]], or even by individual program — granularity that helps [[Definition:Underwriter | underwriters]] and [[Definition:Actuary | actuaries]] identify segments where pricing is inadequate or [[Definition:Risk selection | risk selection]] has drifted. Seasonal and [[Definition:Catastrophe | catastrophe]] volatility can distort single-period readings, so most carriers track rolling averages alongside point-in-time snapshots.<br /> <br /> ⚠️ Because the gross loss ratio ignores reinsurance, it forces a carrier to confront its true loss experience without relying on the safety net of [[Definition:Excess of loss | excess-of-loss]] or [[Definition:Quota share | quota-share]] treaties. This unvarnished perspective is especially critical during [[Definition:Hard market | hard-market]] transitions, when reinsurance pricing rises and carriers may need to retain more risk. A program that appeared profitable on a net basis might reveal troubling gross loss trends that demand re-[[Definition:Pricing | pricing]] or tighter [[Definition:Underwriting guidelines | underwriting guidelines]]. [[Definition:Managing general agent (MGA) | MGAs]] operating under [[Definition:Delegated underwriting authority (DUA) | delegated authority]] are frequently evaluated on this metric by their capacity providers, and a deteriorating gross loss ratio can trigger remediation requirements or even the withdrawal of [[Definition:Binding authority agreement | binding authority]].<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Net loss ratio]]<br /> * [[Definition:Combined ratio]]<br /> * [[Definition:Incurred but not reported (IBNR)]]<br /> * [[Definition:Loss adjustment expense (LAE)]]<br /> * [[Definition:Gross written premium (GWP)]]<br /> * [[Definition:Loss development]]<br /> {{Div col end}}</div>
