The Bogleheads' Guide to Investing

For more than a century, the A. M. Best Company has rated insurance companies from A + + on down. We recommend buying insurance from a company with an A. M. Best rating of A or better. To check the financial strength and overall quality rating of an insurance company, go to www.ambest.com. Other companies that provide insurance ratings are Fitch Ratings (www.fitchratings.com), Moody’s Investor Services (www.moodys.com), and Standard & Poor’s (www.standardandpoors.com).
