MMC Benefits Handbook
When the 409A SRP Benefit Commences
This sub-section describes the payment rules for a SRP benefit that was accrued or vested after December 31, 2004 following a Separation from Service due to a reduction in hours, an extended leave of absence, disability or death. It also describes the payment rules for a survivor benefit when paid to a surviving spouse, same-sex spouse or domestic partner. These SRP benefit payments are subject to Section 409A.
If you have a Grandfathered SRP Benefit (a SRP benefit accrued and vested prior to January 1, 2005) different rules govern the time and form of payment of that portion of your SRP benefit. See "Grandfathered SRP Benefit."
