"Specifically we suggest: [1] Extending the deadline for elections to create or apply funding balances by one month to coincide with the Form 5500 filing deadline; [2] Extending the deadline for elections to reduce (waive) funding balances beyond the end of the plan year; [3] Modifying specific and standing elections to provide greater flexibility by allowing formulaic elections; and ... [4] [P]roviding an additional standing election to waive funding balances under certain circumstances."
