Amounts deferred prior to 2005 are "grandfathered" and are not subject to 409A, unless "the plan under which the deferral is made is materially modified after October 3, 2004." §409A(d)(2)(B). Notice 2005-1, Q/A-18(a) states that "a modification of a plan is a material modification if a benefit or right existing as of October 3, 2004 is enhanced or a new benefit or right is added."
Is it possible that the IRS would view the formation of a Rabbi Trust to fund grandfathered deferrals as a material modification? (Assume the Rabbi Trust would not violate the new rules in 409A re: springing Rabbi Trusts and foreign trusts.)
Instinctively this does not appear to be a material modification for several reasons. The addition of a Rabbi Trust change does not affect the plan itself, but rather the plan's funding mechanism. Also, a Rabbi trust does not protect the participants' assets from creditors, although it does prevent the company from disposing of the assets, except to pay benefits.
The Conference report contains the following in the summary of present law on p. 293: "Arrangements have developed in an effort to provide employees with security for nonqualified deferred compensation, while still allowing deferral of income inclusion." Could this provision of security after 10/3/04 (by adding a Rabbi Trust) be viewed as the enhancement of a right (e.g. the right to receive the benefits)?
I can't help but think that if Rabbi Trusts could not be added to old deferrals without losing their grandfathered status, that the IRS would have said so in the guidance issued to date or informally in the seminars and teleconferences that their representatives have attended. However, I would be interested in hearing others' views on why it is still ok to add a Rabbi trust to pay grandfathered benefits.
Thanks in advance.
