Medical Radiological Group, P.C. v. Commsissioner
The taxpayer established multiple defined benefit pension plans, one for each of its shareholders, with varying normal retirement date provisions.
The consulting actuary assumed a 5% pre-retirement rate of return, used the unit credit actuarial cost method and assumed that the subject participant would retire at age 55. The Internal Revenue Service challenged the actuarial assumptions. No. 20926-92 (U.S.T.C. 1992).
