Health insurers will collect more premiums this year but may generate lower operating profits.

Analysts at Conning Research & Consulting, Hartford, have included that prediction in a review of the health insurance market.

Conning analysts are predicting that total health insurer statutory net operating gain will drop to $21 billion this year, from about $27 billion in 2007, and that the total will continue to about $21 billion per year through 2011.
