In reinsurance , what is the rationale behind reinsurance commission paid by reinsurer to the reinsured

 The commission which paid by reinsurers to the reinsured or the ceding company is almost about25% to35% is  due to the fact that the insurance company had spent a lot of money to handle and manage the risk or business , therefor reinsurers pay this commission to contribute with the insurance company in the administration costs that initially paid by the insurance company.

 Thanking you , wit best wishes.
