Can the non-taxable portion of a distribution from a terminating defined benefit plan which consists solely of previously reported PS-58 costs be rolled over under the same rules that apply to distributions of after-tax employee contributions? These distributions are post EGTRRA and the insurance contracts were surrendered by the Trustee and cash values invested in the plan trust Are the rules any different if the plan is not terminating and the distribution is being paid to a terminated employee?

Form 1099-R instructions seem to say no [and now refer to PS-58 as "cost of current life insurance protection"]
