Under Section 436 of the Internal Revenue Code, a single employer defined benefit plan sponsored by a company in bankruptcy cannot pay any “prohibited payments” (e.g., lump sums, Social Security level income annuity payments) if the plan is less than 100% funded. In June 2012, the IRS issued proposed regulations permitting such a defined benefit plan to be amended to eliminate prohibited payment forms without violating the anti-cutback requirements of Internal Revenue Code Section 411(d)(6) if certain conditions are satisfied.
