Generally, an employer is required to distribute assets from a terminated plan as soon as it is administratively feasible after the date of plan termination.
Whether distributions are made as soon as it is administratively feasible is determined under all the facts and circumstances of a given case, but generally the Internal Revenue Service views this to mean within one year after plan termination (see Rev. Rul. 89-87, 1989-2, C.B. 81).
