Expense Ratio % is the percentage of expenses associated with acquiring, underwriting, and servicing premiums to net premium earned. It can be used to make comparisons between insurance companies as well as measure their performance. An expense ratio below 100% suggests that the premiums an insurance company earned or wrote are more than the expenses it paid to support those premiums.
