Does the proposal change what is meant by "substantial risk of forfeiture"? As I recall, the tax magic behind Rabbi Trusts was that since, in the event the sponsor went belly-up, the assets in the trust would be reachable by the sponsor's creditors, the arrangement was considered to involve a substantial risk of forfeiture, and therefore not currently taxable when the covered individual became vested.
