          Subject: DOD Retiree Health Benefits Liability: Evaluation of DOD's Sensitivity Analysis

          As part of our ongoing work with the Department of Defense (DOD) to prepare for auditable
          financial statements, we have worked extensively with the Office of Actuary and with Health
          Affairs on developing and reporting a reliable estimate for the postemployment health care
          benefits due to military retirees, their dependents, and survivors. To calculate the military
          retiree health care benefits liability, the DOD Office of Actuary has contracted with a private
          sector firm of actuaries and consultants, Milliman & Robertson (M&R), which has
          significant experience in estimating health related liabilities. M&R uses an actuarial model
          that relies on historical information about the retiree population and the numbers, types, and
          costs of medical services provided to them. The model also uses economic, actuarial, and
          other assumptions, such as future interest rates and projected rate increases for medical costs.
          Using the M&R model, DOD estimated its military retiree health care benefits liability to be
          $196 billion in its fiscal year 1999 financial statements.

          To help DOD and its auditors focus their data improvement and audit efforts on the elements
          that have the most significant impact on the resulting liability calculation, we asked the DOD
          Office of Actuary to prepare a sensitivity analysis. A sensitivity analysis identifies key
          elements-data and assumptions as discussed above-and varies a single element while
          holding the others constant to determine what amount of change in that element is required to
          raise or lower the resulting liability by a set amount. In this way, data and assumptions can
          be risk-ranked for decision-making and auditing.

          As agreed to, when the Office of Actuary completed the sensitivity analysis, we (1) evaluated
          its completeness and accuracy and (2) reviewed the methodology used by M&R to calculate
          the retiree health benefits liability, including the actuarial model and individual calculations.
          Because of the technical nature of actuarial projections, we contracted with an independent
          accounting firm, Ernst & Young LLP, to assist us in this work. Our contractor provided
          actuarial expertise in reviewing documentation prepared by the Office of Actuary and by
