How to Choose a Life Insurer
When selecting a life insurance company, prioritize financial strength ratings (AM Best, Moody’s, S&P), policy pricing competitiveness, claim settlement track record, and customer service quality. For term life, comparison shopping across multiple carriers is highly recommended — prices can vary significantly for the same coverage amount and term length. Independent rating agencies like AM Best and J.D. Power’s annual US Life Insurance Study provide objective benchmarks for quality comparison.
