Life insurance companies are rated by a number of different institutions. Therefore, which life insurance companies are top rated will depend on which rating system you choose to use. Here are the main rating institutions available:
A.M. Best
Weiss
Moody's
Fitch
Standard & Poor's
Standard Analytical Service
It may make sense to use multiple rating systems to measure the insurance companies you are interested in.
Life insurance companies are rated by rating agencies. The main four rating agencies are AM Best, Fitch, Standard & Poor's, and Moody's. When you go to a life insurance carrier's home page, there is usually a tab that leads you to their rating. The tab may be titled "Financial Information", "About ___ Insurance Company", "Our History", or something similar. There you will see that company's rating from those rating agencies (or of the rating agencies from which they have been rated). When the rating is shown, it is usually shows what rank it is.
