What does Expense ratio (insurance) mean?

The expense ratio is an insurer's underwriting expenses (commissions to agents and brokers, staff, marketing, systems) divided by premiums, written or earned depending on the convention used. Example: 30 of expenses on 100 of premium is an expense ratio of 30 percent. Direct and digital sales can lower it by cutting commissions. Note that in asset management "expense ratio" means something else: the yearly fee a fund charges, as a share of the money invested.
