The DoW Office of the Actuary (OACT) provides actuarial expertise on all matters relating to military compensation and benefits. OACT delivers actuarial expertise and ensures soundness of the Funds which provide essential benefits to the military community. OACT delivers mission critical objectives on behalf of the Office of Secretary of War and the military services. 

Led by DoW Chief Actuary Pete Zouras with a team of experienced actuaries, OACT performs annual valuations of the military retirement system, education benefits under the Montgomery G.I. Bill, health care for the military retired population, and the Voluntary Separation Incentive program. These valuations include projecting personnel, pay, and benefits, and calculating annual DoW contribution costs, as well as determining program unfunded liabilities and their amortization schedules.

OACT works in support of the DoD Board of Actuaries and the DoD Medicare-Eligible Retiree Health Care Board of Actuaries to fulfil annual statutory funding requirements. OACT provides key input to the DoW agency-wide and component financial statements, led by the DoW Comptroller/CFO. 

The Office also responds to requests for cost estimates of proposed changes in benefits from DoW, other government agencies, and military service support groups.
