Humana is an attractive acquisition target for insurers who want its booming Medicare Advantage business. With 12,000 employees, Humana is also the second-largest company in Louisville, Kentucky--and Mayor Greg Fischer (D) and Gov. Steve Beshear (D) said they are committed to keeping the company in the city, WDRB reported. Beshear said the insurer has been a "mainstay" of the Louisville economy for a long time, but he and Fischer admitted that there may not be much they can do if Humana is sold to an out-of-state firm. Aetna, Anthem and Cigna are rumored to be interested in acquiring Humana, FierceHealthPayer previously reported. Article
