I mostly agree BUT:
I am dubious of the ratings companies. How is it that Weiss has Banner and Sunlife as "D" rated companies that are among the ten worst among billion dollar plus life insurers yet Best's has them both as A+? Don't even get me started about the COMDEX. The big rating agencies, I believer, rely too much on the size of the company and not the profit margin, general account performance, and lapse rates.
Maybe, but with around 130 companies (last time I checked) Best's rated A+ or A++, why go lower? Your client may not ask or even be aware of a company's relative ratings, But I know.
