<p><b>New page</b></p><div>🛡️ '''Maximum net retention''' is the largest amount of [[Definition:Loss | loss]] exposure that an [[Definition:Insurance carrier | insurer]] or [[Definition:Reinsurer | reinsurer]] is prepared to retain on its own account for any single risk or event after all [[Definition:Reinsurance | reinsurance]] and [[Definition:Retrocession | retrocession]] protections have been applied. It represents a core risk appetite parameter — a ceiling that ensures no individual loss can disproportionately erode the company's [[Definition:Capital | capital]] or [[Definition:Surplus | surplus]]. Boards and senior management set maximum net retention limits as part of their broader [[Definition:Risk appetite | risk appetite]] framework, and these limits are closely scrutinized by [[Definition:Insurance regulator | regulators]], [[Definition:Rating agency | rating agencies]], and [[Definition:Capital provider | capital providers]].<br />
<br />
⚙️ Determining the appropriate maximum net retention involves balancing several considerations. An insurer begins with its [[Definition:Gross retention | gross]] exposure — the full limit it has written on a given policy or risk — and then subtracts the portions ceded through its [[Definition:Reinsurance program | reinsurance program]], which may include [[Definition:Quota share | quota share treaties]], [[Definition:Surplus treaty | surplus treaties]], [[Definition:Excess of loss reinsurance | excess of loss]] covers, and [[Definition:Facultative reinsurance | facultative placements]]. The residual amount is the net retention. Setting the maximum involves actuarial analysis of the insurer's [[Definition:Probable maximum loss (PML) | probable maximum loss]], capital adequacy under applicable regulatory frameworks — whether [[Definition:Solvency II | Solvency II]], [[Definition:Risk-based capital (RBC) | RBC]], [[Definition:C-ROSS | C-ROSS]], or others — and stress-testing against severe but plausible scenarios. A large, well-capitalized global insurer may set its maximum net retention at tens of millions of dollars per risk, whereas a smaller regional carrier might cap it at a fraction of that figure.<br />
<br />
📊 Monitoring adherence to maximum net retention limits is an ongoing operational discipline, not a one-time calculation. [[Definition:Underwriting | Underwriting]] teams must verify that each risk they write falls within the company's retention parameters before binding coverage, and the [[Definition:Ceded reinsurance | reinsurance cession]] must be confirmed and documented. Breaches — whether due to underwriting error, reinsurance exhaustion following a major [[Definition:Catastrophe | catastrophe]], or the failure of a reinsurer to pay — can leave the insurer holding more exposure than its capital structure was designed to absorb. For this reason, companies track net retentions in real time using [[Definition:Underwriting platform | underwriting platforms]] and [[Definition:Exposure management | exposure management]] systems, and many regulators require periodic reporting of largest net retentions as part of their supervisory review process.<br />
