I am pretty sure of this, but just to confirm, an individual participant may not, under 403(B)(8), rollover 403(B) assets into a 401(k)if their 501©(3)company now starts up a 401(k), correct? I think the assets must be maintained separately. Thanks for any comments.

You are correct. However, the recently passed (but vetoed) tax bill would have changed this result. And the consensus among practitioners is that the benefits provisions of that bill are noncontroversial enough so that they will show up in whatever tax bill passes. So when is one going to pass? Sorry, but I'd need a crystal ball to predict that one!
