(Reuters) - Bruce Broussard took over as chief executive of Humana Inc in January, just in time to steer the health insurer's entry onto the health insurance exchanges created by President Barack Obama's reform law. Humana plans to sell subsidized insurance plans in 14 states, including Arizona, Colorado, Florida and Kentucky, where it is based, about the same number of states as rivals like WellPoint Inc and Aetna Inc. The exchanges are expected to bring in 7 million people in 2014. Insurers must offer plans to any individual who applies, regardless of prior health problems. The government will provide subsidies to people who earn up to 400 percent of the federal poverty level, or $94,200 for a family of four.
