For insurance companies, determining insurance rates is a important, though potentially tricky, matter. On the one hand, insurance companies need to charge rates that ensure they cover costs and reap some profit. On the other hand, there is also the importance of maintaining one’s customer base, and also complying with state law.
When it comes to setting insurance rates, Michigan’s no-fault insurance system has been characterized as a “file and use” system. Under this system, insurance companies file their proposed rates with the Department of Insurance and Financial Services. The Michigan Insurance Commissioner then has the opportunity to object to “excessive” rates. If no such objection is made, the insurance company can go ahead and charge those rates to consumers.
