Subject Premium
The total premium amount on which reinsurance or excess insurance calculations are based, before any deductions or adjustments. It serves as the foundation for determining reinsurance costs and profit-sharing arrangements.
Example
“The reinsurance treaty specified that the reinsurer would receive 25% of the subject premium for property insurance policies exceeding $1 million in coverage.”
Memory Tip
Subject premium is the premium 'subject to' sharing - like being subject to taxes, this premium is subject to reinsurance splits.
Why It Matters
Understanding subject premium helps explain why insurance costs vary and how risk is distributed across multiple companies. It affects the financial stability of your insurance company and ultimately influences premium pricing and claims-paying ability.
Common Misconception
Many people think subject premium is the same as the premium they pay. Subject premium is actually the gross premium before deductions and is used primarily for reinsurance calculations, while your actual premium may include various adjustments and fees not included in the subject premium.
In Practice
An insurance company collects $10 million in subject premium on commercial property policies. Under their reinsurance treaty, they cede 30% of this premium ($3 million) to reinsurers. In return, reinsurers pay a 25% ceding commission ($750,000) back to the insurer for expenses. The insurer keeps $7.75 million in net premium but transfers 30% of the risk to reinsurers, improving their capital efficiency and risk management.
Etymology
From Latin 'subjectus' meaning 'placed under' and 'premium' meaning 'reward.' The term emerged in reinsurance practices in the early 20th century to describe premiums 'subject to' reinsurance arrangements.
