Of QVECs, VDECs and Minimum Distributions

[rocknrolls2]

For purposes of the minimum distribution rules, are QVECs (otherwise known as VDECs or DECs) subject to the IRA minimum distribution rules or the qualified plan minimum distribution rules? This is critical in 2 respects: the ability or inability of an active employee to defer the required beginning date to retirement and the ability of a deceased spouse to consider the QVEC as his/her own.

My research has not disclosed any answer. Under ERTA proposed regs, no deductible contributions could be made to QVECs after 70 1/2. However, for distribution purposes, the QVEC was subject to the rules of Code Section 402(suggesting it was a type of qualified plan).

This is not an academic question, so I would sincerely appreciate any thoughts anyone may have on this subject.
