What do A.M. Best’s Letter Gradations mean?
| A++ and A+ | Superior | Companies with either of these ratings are among the top-rated in the industry. |
| A and A- | Excellent | These companies show a high degree of stability and a positive long-term outlook. |
| B++ and B+ | Good | These companies are stable but have room for improvement. The long-term outlook may be unsure. |
| B and B- | Fair | While currently stable, these companies have a lot of room for financial improvement. Companies rated below a B+ may not be the best choices for long-term insurance policies but may be suitable for short-term policies such as car insurance. |
| C++ and C+ | Marginal | Indicates that the company is going through some sort of financial turmoil. Consumer investment should only be made with extreme caution. Investors may be more interested in this rating because it shows the potential for future gains. |
| C and C- | Weak | Indicates a company that is going through financial problems of one sort or another. Not a good choice for purchasing an insurance policy. |
| D | Poor | This company has suffered some sort of major financial stress and is currently on shaky financial ground. Companies with a rating of D may not be suitable for insurance purchases or long-term investments. |
| E | Under regulatory supervision | Indicates a company that is being investigated or administrated by an outside agency. |
| F | In liquidation | Indicates a company that is being liquidated to pay debts. An F-rated company is probably not allowed to sell insurance products, and would not be a wise investment. |
| S | Suspended | This company, for whatever reason, is no longer accepting new customers or investments. |
What does it mean if an insurance carrier doesn’t have a rating?
Just because you cannot find a rating for any particular company from this rating agency, do not assume that the company is insolvent or even in poor financial health. There are many reasons why a rating may not be available, including the company is a subsidiary of a larger firm, lack of current information during the rating update, or company changes in name or ownership.
Other major rating agencies may have insight into the performance of a specific company; you can also turn to the BBB Business Profile of a particular insurance provider. This could be a good indicator of whether a provider will have the ability and financial strength to sustain its ongoing insurance operations, provide insurance coverage, and fulfilling its insurance obligations. You can look for signs of poor operating performance or financial performance.

Why do ratings change often?
Ratings for insurance have to be updated frequently in order to be kept up to date. Companies that have less than perfect ratings but which are known to be going through restructuring, selling portions of the company, or other financial transactions may be slated for a rating upgrade soon. It is not unusual for a rating to drop during a tumultuous economic season, and such temporary downgrades seldom last more than one or two rating periods.
