An employer contribution shall not be treated as an elective deferral described in subparagraph (C) if under the salary reduction agreement such contribution is made pursuant to a one-time irrevocable election made by the employee at the time of initial eligibility to participate in the agreement or is made pursuant to a similar arrangement involving a one-time irrevocable election specified in regulations.
