Description: While most actuaries work for companies and have as a primary objective the financial success of their employers, regulatory actuaries primarily serve the public interest. In part one of this presentation, we will explore the role of actuaries whose priority is to serve the public interest. Regulation is developed by a deliberative process that includes regulators, the American Academy of Actuaries, trade associations and the companies that will be affected by the regulation. In part two of this session, we will present a series of vignettes each focusing on recent updates to the Valuation Manual. At the conclusion of the session, attendees will have a deeper appreciation of what goes on behind the scenes in the development of regulation.
