Richard, my version is the 5th edition, copyright 1999. The article starts on page 579. It's tough to find materials that address these issues as in as much depth. It's titled "Planning Opportunities to Maximize Benefits for Key Employees Under Qualified Defined Benefit Plans", but it covers cross tested DC plan testing as well.
Well worth locating.
And, let's thank Mike Preston for lending his expertise to the discussion as well. Kind of like the old EF Hutton Commercials, "when EF Hutton speaks, people listen".
