Insurance Term - Operating Ratio (IRIS)

It is the combined ratio less the net investment income ratio (net investment income to net premiums earned). The operating ratio measures a company’s overall operational profitability from underwriting and investment activities. This ratio does not reflect other operating income/expenses, capital gains or income taxes. An operating ratio of more than 100 indicates a company is unable to generate profits from its underwriting and investment activities.
