A rating agency says it is about to increase the marks it has assigned many U.S. health insurers but lower marks for others.
The Chicago office of Fitch Ratings has published updated rating criteria for U.S. health insurers.
The updates reflect changes the company made in its Quantitative-Insurer Financial Strength rating methods for life insurers and property-casualty insurers in 2005.
Fitch expects to publish ratings for about 220 health insurers within the next month.
