NEW YORK, January 13, 1998 – American International Group, Inc. (AIG) and United HealthCare Corporation have formed AIG United HealthCare, LLC, a joint venture company that will establish jointly-owned health care services organizations initially in selected Asian countries to provide progressive health care management services.

AIG and United HealthCare will each have 50 percent ownership in AIG United HealthCare, LLC. The joint venture’s first jointly-owned health care services organization, AIA United HealthCare Limited, has been established in Hong Kong and expects to begin enrolling members in the first quarter of 1998.

“This joint venture presents a great opportunity for AIG and United HealthCare to provide the proven health care management and cost containment techniques that the medical care markets in Asia will increasingly require,” said Gregory Arms, Director, AIG Group Management Division. “By bringing together AIG’s strong insurance and employee benefits franchise in these regions with United HealthCare’s proven expertise in providing quality, innovative health coverage, we believe we can help employers provide affordable health care benefits and access to quality health care services.”

Henry Loubet, CEO, Pacific Region, United HealthCare Corporation, said, “Health care systems around the world are starting to migrate to the health plan models and services found successful by United HealthCare. We will work closely with AIG – already a dominant force in the Asian insurance market – to tailor programs to meet the distinct needs of these markets.
