President

Gordon R. Trapnell is a nationally recognized expert in analyzing the feasibility and estimating the cost of private and public insurance programs. He has prepared cost estimates for major new federal insurance initiatives, providing the data needed by public officials to reach important policy decisions. His analysis has served as the basis for evaluating the major national health insurance proposals developed by the Administration and Congress.

Mr. Trapnell has extensive experience analyzing the actuarial problems faced by public sector insurance and employee benefit programs, especially Medicaid and Medicare. He has been retained by the Congressional Budget Office by every Administration in the past 40 years and by a variety of other interested parties to analyze the cost and financial impacts of major proposals to change the financing of U.S. health care.  His estimates have also been used to analyze the impact of proposals to reform small group and individual health insurance markets.

Mr. Trapnell began his actuarial career at the Life Insurance Company of Virginia. As the group actuary, he was responsible for developing the benefit package and premium rates for Virginia-North Carolina 65, an open enrollment program for senior citizens that predated the Medicare program. Prior to forming ARC, he was the senior actuary responsible for Medicare in the Social Security Administration. In this capacity, he was responsible for preparing long-range Medicare cost estimates, determining tax rates and enrollee premiums, and estimating the effect of proposed legislative changes to the program. He also assisted the staff at the Congressional Committees concerned with social insurance in proposing and drafting new legislation.

Mr. Trapnell is a Fellow of the Society of Actuaries and Member of the American Academy of Actuaries.  He holds a B.S. degree in mathematics from the University of Virginia and completed preliminary examinations for a Ph.D. in finance and health economics at the Massachusetts Institute of Technology.

Actuarial Research Corporation’s long-time Vice President, Jim Mays, passed away unexpectedly on December 15, 2016.

Jim joined ARC as one of its first employees, in 1979, following the conclusion of his studies at UVA.  Over the course of the next 37 years, he became known for his work in quantitative analysis of health care financing structures. He directed the development of a data base of employer-sponsored health insurance plans which has been used to examine the effect of proposals to alter the tax exclusion for employer payments for health insurance, developed a quantitative model that allows simulation of the effects of small group rate regulation reform, and developed algorithms for incorporating health risk adjustors into rate reform.

Jim participated in all of the major domestic health initiatives of the past three decades.  He worked on developing comprehensive premium estimates for the Minimum Health Benefits for All Workers Act of 1987, and since then was actively involved in analyzing implementation problems of mandated coverage proposals.  During 1992, he served as one of two non-government members of the Bush Administration’s White House Task Force on Health Risk Pooling, and in 1993 he was a member of the Clinton Administration’s Health Reform Task Force.  Jim worked with the US Department of Health and Human Services to develop regulatory impact analyses for privacy regulations under the 1996 Health Insurance Portability and Accountability Act (HIPAA), and he assisted the Department in analysis of Medicare beneficiaries’ prescription drug spending and in its presidentially‑mandated study of prescription drug pricing. He assisted the Medicare Office of the Actuary in modeling enrollee behavior under alternative premium support models tied to the Obama Administration comprehensive Medicare reform.

Jim’s influence extended beyond the United States.  He shared his expertise with the World Bank in the Philippines, Turkey, Egypt, Saudi Arabia, Oman, Bahrain, and Qatar, developing and refining models to simulate the effects of changes in health care delivery and financing.  His ability to mediate between the worlds of policy and data was respected and sought after worldwide.

Closer to home, Jim was a valued director and mentor at ARC, guiding young analysts as they began their careers in the analysis of fast-growing and rapidly evolving health care financing systems. His soft-spoken manner, low‑key managerial style, and dry sense of humor did much to cushion the fast pace and high pressure of the work he directed.

Throughout his life, Jim was an accomplished analyst, a subject-matter expert, a leader, a mentor, and a friend. His quiet accomplishments have strengthened health care systems here and around the world. An organ and tissue donor, Jim continues to serve others even in death.
