Definition - What does Unearned Premiums mean?
Unearned premiums are premiums that an insurance company receives before it provide coverage for a specific period. In other words, they constitute premiums a policyholder pays in advance. Because the insurance company has not actually provided coverage for unearned premiums, they are refundable should the policy be canceled.
Insuranceopedia explains Unearned Premiums
For example, a company pays for 10 years of product liability insurance in one lump sum for a policy that costs $5,000 per year. After three years, the insurance company would have $15,000 of earned premiums and $35,000 of unearned premiums.
