<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>💲 &#039;&#039;&#039;Rate on line (ROL)&#039;&#039;&#039; is a pricing metric used in [[Definition:Reinsurance | reinsurance]] that expresses the [[Definition:Reinsurance premium | reinsurance premium]] as a percentage of the [[Definition:Limit | limit]] of coverage provided by a particular layer of a [[Definition:Reinsurance treaty | reinsurance treaty]] or [[Definition:Facultative reinsurance | facultative placement]]. If a reinsurer provides $10 million of limit and charges a $2 million premium, the ROL is 20 percent. Simple in construction, this ratio is the universal shorthand by which [[Definition:Reinsurer | reinsurers]], [[Definition:Ceding company | cedents]], and [[Definition:Reinsurance broker | reinsurance brokers]] compare the price of [[Definition:Excess of loss reinsurance | excess of loss]] protection across transactions, layers, perils, and market cycles.<br /> <br /> 📊 ROL is most commonly applied to [[Definition:Catastrophe reinsurance | catastrophe]] and per-risk excess of loss programs, where the relationship between premium paid and limit purchased captures the market&#039;s assessment of [[Definition:Expected loss | expected loss]] frequency and severity for that layer. A rising ROL environment signals that reinsurers are demanding higher compensation for deploying [[Definition:Underwriting capacity | capacity]] — often driven by recent [[Definition:Catastrophe loss | catastrophe losses]], reduced supply from [[Definition:Retrocession | retrocession]] markets, or increased [[Definition:Loss trend | loss trends]]. Conversely, falling ROLs indicate abundant capacity and competitive pressure. Brokers track ROL indices year over year to benchmark renewal outcomes, and cedents use ROL analysis when structuring their [[Definition:Reinsurance program | reinsurance programs]] to determine the most capital-efficient attachment points and layer sizes.<br /> <br /> 🧭 Beyond its role as a pricing benchmark, ROL serves as a barometer for the broader health of [[Definition:Reinsurance | reinsurance]] markets. [[Definition:Rating agency | Rating agencies]] and investors in [[Definition:Insurance-linked securities (ILS) | insurance-linked securities]] monitor aggregate ROL trends to assess whether reinsurers are being adequately compensated for the risk they assume. When ROLs fall below [[Definition:Actuary | actuarially]] indicated levels for extended periods, it often foreshadows future [[Definition:Underwriting loss | underwriting losses]] and a correction — the onset of [[Definition:Rate hardening | rate hardening]]. For [[Definition:Ceding company | cedents]] structuring programs, understanding ROL dynamics across layers helps them optimize the trade-off between [[Definition:Net retention | retention]] levels and the cost of transferred risk, making it an indispensable input in capital management and [[Definition:Enterprise risk management (ERM) | enterprise risk management]] decisions.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Excess of loss reinsurance]]<br /> * [[Definition:Catastrophe reinsurance]]<br /> * [[Definition:Reinsurance premium]]<br /> * [[Definition:Rate hardening]]<br /> * [[Definition:Reinsurance program]]<br /> * [[Definition:Insurance-linked securities (ILS)]]<br /> {{Div col end}}</div>
