<p><b>New page</b></p><div>📋 '''Gross net premium income (GNPI)''' is a measure used predominantly in [[Definition:Reinsurance | reinsurance]] transactions to quantify the [[Definition:Premium | premium]] base on which reinsurance pricing and cession calculations are applied. Specifically, it represents the [[Definition:Ceding company | ceding company's]] gross premium income after deducting the premiums attributable to other reinsurance arrangements that inure to the benefit of the treaty in question — essentially, it is gross premium minus the premium ceded under reinsurances that reduce the exposure before the subject treaty attaches. GNPI is a term deeply embedded in reinsurance contract language and is encountered most often in [[Definition:Treaty reinsurance | treaty reinsurance]] agreements, particularly [[Definition:Excess of loss reinsurance | excess of loss]] and [[Definition:Stop-loss reinsurance | stop-loss]] contracts where the premium charged to the cedant is expressed as a percentage of GNPI.<br />
<br />
🔢 The calculation starts with the ceding insurer's total gross written or earned premium for the lines of business covered by the treaty, then subtracts premiums ceded to reinsurance programs that are deemed to inure — that is, reinsurance protections whose recoveries reduce the exposure flowing into the treaty being priced. For example, if an insurer writes $200 million in gross premium for its property book and cedes $30 million to a [[Definition:Quota share reinsurance | quota share]] treaty that inures to the benefit of its excess of loss program, the GNPI for that excess of loss treaty would be $170 million. The reinsurance rate — say, 5% — would then be applied to this $170 million base, producing a reinsurance premium of $8.5 million. Precisely which inuring reinsurances are deducted is defined in the treaty wording and can be a point of negotiation between cedants and [[Definition:Reinsurer | reinsurers]], as it directly affects the premium volume on which the rate operates.<br />
<br />
💡 GNPI matters because it serves as the common currency for pricing and settling reinsurance treaties across global markets. A reinsurer in Zurich, a [[Definition:Retrocessionaire | retrocessionaire]] in Bermuda, and a cedant in Tokyo all rely on a shared understanding of GNPI to ensure that contractual obligations are calculated consistently. Disputes can arise when the definition of inuring reinsurances is ambiguous or when changes to a cedant's underlying reinsurance program alter the GNPI base mid-term, making precise drafting of treaty terms critical. For [[Definition:Reinsurance broker | reinsurance brokers]] managing placements, accurately projecting GNPI is essential for setting minimum and deposit premiums, and deviations between estimated and actual GNPI at year-end trigger [[Definition:Premium adjustment | premium adjustments]] that flow through to all participating reinsurers.<br />
