BTW, if your concern is paying taxes, don't forget that you can defer taxes by using a rollover to an IRA. If you want to later roll that amount somewhere else, it may be best to use an IRA that is separate from all your other IRA's. You can order a copy of IRS Publication 590 at www.irs.gov.
Stop? Not per se, but it is (in my observation) pretty common for DB plans to have language that offsets benefits received against future accruals. The net effect is almost always a benefit (to that employee/retiree) that does not increase. This characteristic helps make 401(a)(36) a valuable option to encourage phased early retirement.
ERISA section 4041 defines two types of terminations: standard and distress. Section 4042 discusses a termination inititated by the PBGC. An involuntary termination has (approximately) the same net effect as a distress termination, but there is no "application" for the former.
Notice the prominent use of the word "bankruptcy" in discussing a distress termination.

My understanding of "final 5500" is a requirement of zero assets and zero participants. Unless the "money in the trust" exists only because the (for example 12/29/08) check has not yet been cashed by 12/31/08, then you don't have zero assets at EOY. Anyone else have other information?
From a non-lawyer: advice from J Simmons sounds very good.
Perhaps the plan should consider rejecting the QDRO (assuming one is ever delivered), stating that the benefit has been paid per the terms of the plan. (Of course, this assumes the plan administrator did not have knowledge of a possible QDRO.)
I can recommend several, from a variety of states, as many readers/users of these Boards could. E-mail me, if that is what you need. But, as implied earlier, it may be more useful to get recommendations from someone you know.
I found no specific statement that it is "still in effect". However, it is clearly the pattern of IRS regulation, and now the express intent of PPA, to prefer using MV of assets. Some sections of Rev Proc 2000-40 are no longer applicable, but it is extremely unlikely the IRS would void section 3.10.
