Mercer LLC, a subsidiary of Marsh & McLennan Cos., has launched a new Web portal, Mercer/Signal: US Health Care Reform, designed to be a one-stop source to help employers stay up to date on a wide range of topics related to health care reform. Tracy Watts, Mercer's U.S. Health Care Reform leader, and Beth Umland, director of research for Employee Health & Benefits at Mercer, are leading the new content portal, supported by a team of Mercer subject matter experts representing all facets of health reform and health benefits. Visitors are asked to register, but there is no charge. Content from the portal also will be shared through LinkedIn and Twitter.
