The unearned premium reserve is an item that appears on insurers balance sheets. It shows the total amount of premiums written but not yet earned. This should be considered together with the unexpired risk reserve if the latter has been created.
This is a technical reserve that balances the difference between premium earned and premium written.
The unearned premium reserve is a reflection, on the balance sheet, of the accrual of premium revenue to the risk taken to earn it. As such, it is similar in purpose to deferred income in the accounts of a non-financial company.
