For other normal retirement ages the conversion factor shall be determined in accordance with regulations prescribed by the Secretary of the Treasury or his delegate. (C) For purposes of this subsection, the term "accumulated contributions" means the total of— (i) all mandatory contributions made by the employee, (ii) interest (if any) under the plan to the end of the last plan year to which section 203(a)(2) does not apply (by reason of the applicable effective date), and (iii) interest on the sum of the amounts determined under clauses (i) and (ii) compounded annually at the rate of 5 percent per annum from the beginning of the first plan year to which section 203(a)(2) applies (by reason of the applicable effective date) to the date upon which the employee would attain normal retirement age.
