“Des Moines-based American Enterprise Group announced Thursday that it will exit the individual major medical insurance market, making it the 13th company to pull out of some portion of Iowa’s health insurance business since June 2010. The move means 110 employees will lose their jobs over the next three years — 40 in Des Moines and 70 in Omaha. It also underscores the widespread anxiety among insurance companies over the raft of regulation resulting from the health care overhaul bill.”
