What is the largest insurance rating company in the United States? Why is its rating important?

Meanwhile, Fitch uses specific rating scales to evaluate the credibility and financial stability of an insurer. The “AAA” rating is Fitch’s highest credit rating, while the “D” rating is the lowest, meaning the company defaults to the default. Fitch has many other rating levels. For example, a “BBB” rating represents a good credit rating and has sufficient resources to meet financial obligations.
