Description: This article is about a seminar held on October 30, 1997 to discuss mortality improvement in the NAFTA countries and the impact of such improvements on the financing and benefit adequacy of the countries’ individual social security systems. The gathering of about 80 researchers from a variety of disciplines served as a type of summit meeting on the NAFTA countries’ mortality projections. The seminar was Phase 2 of a three-phase SOA research project, 'Impact of Mortality Improvement on Social Security: Canada, Mexico, and the United States.' The project is intended to provide some guidance for appropriate governmental bodies to use in determining future financing and benefit needs for social security. It is sponsored by the SOA, The Actuarial Foundation [formerly the SOA Foundation], the Retirement Research Foundation, the American Society of Pension Actuaries, the social security administration of each NAFTA country, and the Pension Research Council.
