<p><b>New page</b></p><div>🛡️ '''Net retention''' refers to the amount of [[Definition:Risk | risk]] — expressed either as a dollar limit per occurrence or as a proportion of [[Definition:Premium | premium]] — that an [[Definition:Insurance carrier | insurance carrier]] or [[Definition:Reinsurer | reinsurer]] keeps on its own books after all outward [[Definition:Reinsurance | reinsurance]] arrangements have been applied. In essence, it measures the insurer's true skin in the game: the maximum [[Definition:Loss | loss]] exposure the company would bear from a single event or across a portfolio before its reinsurance program responds. The concept is fundamental to [[Definition:Capital management | capital management]], [[Definition:Solvency | solvency]] analysis, and strategic portfolio construction.<br />
<br />
🔍 Determining net retention involves mapping every layer of an insurer's reinsurance program — [[Definition:Quota share reinsurance | quota share treaties]], [[Definition:Excess of loss reinsurance | excess-of-loss covers]], and [[Definition:Facultative reinsurance | facultative placements]] — against the gross risk assumed. Consider a carrier that writes a $10 million commercial property [[Definition:Policy | policy]], cedes 30% under a quota share, and purchases excess-of-loss protection that attaches at $3 million. After the quota share, the carrier's net position is $7 million; the excess-of-loss cover then caps its per-occurrence exposure at $3 million. That $3 million figure is the net retention. Carriers regularly stress-test these figures under [[Definition:Catastrophe modeling | catastrophe models]] and [[Definition:Probable maximum loss (PML) | probable maximum loss]] scenarios to ensure the retained exposure aligns with available [[Definition:Surplus | surplus]] and risk appetite.<br />
<br />
⚖️ Regulators and [[Definition:Rating agency | rating agencies]] scrutinize net retention closely because it reveals how much volatility remains on the insurer's balance sheet. A company with aggressive retentions relative to its capital base faces heightened [[Definition:Ruin probability | ruin probability]], while overly conservative retentions — ceding too much to reinsurers — may compress margins and signal dependence on external capacity. Striking the right balance is a core discipline of [[Definition:Enterprise risk management (ERM) | enterprise risk management]], and shifts in net retention levels often signal strategic pivots, such as growing confidence in a [[Definition:Line of business | line of business]] or a response to hardening [[Definition:Reinsurance market | reinsurance markets]] that make purchasing outward cover more expensive.<br />
