AM Best Rating Scale

Written by Scott W Johnson

​The AM Best Rating scale is a form of a Financial Ratings Scale that is specific to the AM Best Brand.   Below please find detailed information concerning their ratings and classifications.

Since AM Best is the creator of the IFS rating classification and since they are the only credit rating agency to specialize in life insurance ratings, they seem to be the rater that most of the life insurers tend to focus on. Therefore a post that goes into detail of the rating scale is important.  Our Ultimate AM Rating Scale Infographic is below.

Financial Strength Ratings focus on the insurer's ability to pay claims.​

Almost all the information from this article is pulled directly from AM Best .com.  The document most often referred to is the AM Best Financial Strength Rating Guide.

The AM Best Preamble:

One of the biggest things to know, before learning about the rating scales is that AM Best is expressing an 'opinion' about the insured's ability to pay out claims.   The FSR rating is "not a recommendation to purchase."  As with any credit rating agency, its always possible that the rating agency could be incorrect about their assessment.   This is one of the reasons that we always suggest that you check Financial Strength Ratings with at least two Credit Rating Agencies.

Please also understand that we are discussing most specifically a Financial Strength Ratings scale and Not a Credit Rating Scale.  For AM Best their Credit Ratings are often known by Issuer Credit Ratings.  Those are distinct and different.  In other words they are different.

Financial Strength Rating Scale

The AM Best Rating Scale:

When reading about the AM Best rating scale take great care not confuse the one plus vs the two plusses. Confusingly ++ is considered better than +.  In other words an AM Best A++ is considered the very best Financial Strength Rating that they give out.  And A+ is considered to be the second best.

AMBEST Rating Scale

AM Best Poor Rating:

D & -

An AM Best "poor" rating is a terrible terrible score for any insurance company to receive.  I can not imagine any reason to buy from any insurer that has a D or "-" rating from AM Best.  Steer clear of these companies.

AM Best Weak Rating:

C & C-

A Weak ranking is a very very bad score to receive and although it is clearly better than their poor score, it should mean that you consider insurance from an carrier in this rating.  I would advise clients to also stear clear of this rating level.

AM Best Marginal Rating:

C+ & C++

Although a marginal rating sounds OK, it is really not.   The C+ and C++ may be ok for Geometry but its really bad news for your life insurer.   There is little reason to consider these insurance companies.

AM Best Fair Rating:

B & B-

The Fair rating is the first AM Best rating that I could imagine in some scenario possibly suggesting that someone buy insurance from.  However still, this rating is poor enough and with so many carriers I am not certain why this would be necessary.   Our general opinion is to stay away from this category level if you can.

AM Best Good Rating:

B+ & B++

Although the word good sounds fine, its still not good enough.   Often these are solid life insurers that have fallen.  The B+ and B++ rated insurer is a far off possibility, but with so many A rated carriers, its not very likely.

AM Best Excellent Rating:

A- & A

The AM Best Excellent rating is the lowest rated level that we generally recommend for the purchase of life insurance.  AM Best Excellent rated life insurers are insurers that have an "excellent ability to meet their insurance obligations."

AM Best Superior Rating​:

A+ & A++

The Superior category is the most desirable category to be in.  Life Insurance companies know this and almost all of them work very diligently to get to this rating level, whether its A++ or A+.  Between both the Superior and Excellent Best ratings there are literally hundreds of life insurers to choose from.

The AM Best Non Rating Scale:

Non Rated AM Best

Whole Vs Term does not recommend purchasing life insurance from any non rated company. However for the purposes of clarity and thoroughness with the AM Best Ratings Scale we do recommend understanding the non rated categories.

AM Best Non Rating Symbol E:

The AM Best E rating is reserved for insurers that are "under a significant form of regulatory supervision, control, or restraint."  As to what exactly a non significant form of regularly supervision is we can not say.   I would clearly not purchase any form of any insurance product with this AM Best rating.

AM Best Non Rating Symbol F:

This Financial Strength Rating is held for insurance companies that are  in a "publicly placed in liquidation by a court of law or a by a forced liquidation."   This rating is about as bad as it gets.   These are insurance companies going under, but in a regulatory fashion.  Do not buy any form of insurance from any insuer with the F Financial Strength Rating.

AM Best Non Rating Symbol S:

The AM Best S rating is a bit less clear on its exact meaning.   It is held for firms who experience "sudden and significant events" that "impact operations and rating implications" that can not be "evaluated."   This is another form of Financial Strength Rating to clearly not buy a product from.

AM Best Non Rating Symbol NR:

The Financial Strength Rating NR - merely means that it is "Not Rated."   Although this is not necessarily bad news, it would seem odd to purchase any insurance product from any insurance company that has yet to be rated.  Although potentially understandable for some sort of insurance conglomerate that is splitting up or splitting off, I would still generally recommend not buying any form of insurance from this type of company as well.

AM Best Ratings Disclosures:

Please read AM Best's full set of disclosures whenever reviewing the FSR ratings.  AM Best Financial Strength Ratings are an opinion of the "issuer's obligations."

AM Best Roman Numerals:

Best also categorizes insurer's by their size category.  Classes I to XV, with XV being the largest and I being the smallest.  In my opinion its hard to see how this categorization helps average consumers much, but we present this information with the intention of sharing the full story.
