Members of the conference provide consulting services to businesses and the public on individual life and health insurance, group insurance, social insurance, pensions, other post-employment benefits, and property/casualty insurance. Members work for federal, state, and local governments; consulting and accounting firms; corporations; life insurance firms; and investment firms.
