I have a multiple employer plan. I test the companies separately, but do I have to submit separate 5500's for them? It seems in the past they were filing two returns, but in 2006 it was reported that company B "transferred" its plan assets to company A. In 2007, only one for was done with the combined assets.

Mark Box A(3) of Form 5500 for a multiple employer plan, and file only one return.
