Gross Net Written Premium Income

Insurance companies often offload some of their risk to other firms, known as reinsurers. Gross net written premium income is a key figure that these companies use to divvy up your premium payment.

You run a trampoline amusement park/broken glass depository. Your customers end up reporting a lot of injuries. Your insurance company doesn't want all that risk on its book, so it takes on a reinsurer.

You pay a premium to your insurance company in exchange for coverage...that's the check you write every month to the insurer. Your insurer then needs to send some part of that dough to the reinsurance firm.

The figure used to determine the reinsurer’s share is called gross net written premium income. It's the base figure the insurance companies use to determine the amount each of them are due. It includes the amount you pay, before any expenses or other costs are deducted.
