Questions this course answers

What is the central purpose of an insurance premium?

A premium is the price paid for the insurer's contractual promise, subject to the policy's coverage terms.

What does underwriting primarily decide?

Underwriting evaluates eligibility, coverage, conditions, and risk classification before or alongside rating.

What do frequency and severity measure?

Frequency concerns claim incidence; severity concerns the size or cost of a claim.

Why can a higher deductible reduce a premium?

A deductible reduces the portion of each covered loss the insurer expects to pay, all else equal.

What is reinsurance?

Reinsurance lets a primary insurer transfer defined risks or loss layers to another insurer for a payment.
