Paul I, thank you for suggesting some other factors.
Among many points a fiduciary might consider, one I find at least question-raising is that neither the auto-portability provider nor the receiving plan’s recordkeeper seems obligated to evaluate whether the receiving plan is prudently, or even lawfully, administered.
What if, under a next employer’s plan, the expenses borne by a plan account are worse than those charged to a default IRA?
What if none of a new employer’s people handling the plan’s assets is covered by fidelity-bond insurance, one of them steals the new participant’s account, and the employer is judgment-proof?
It’s hard enough to decide defaults for the plan a fiduciary manages. But how does a fiduciary prudently say yes to defaults about an unknown plan that’s beyond the former employer’s control?
Yet, I also can imagine some situations under which not getting auto-portability default contributions might weaken a plan for some of its participants. I wonder whether a plan’s fiduciary has a responsibility to consider that.
And there are impartiality conflicts: Even within one plan, auto-portability could help some participants, and could harm some others.
I guess the analysis might wait until there’s a live candidate with real facts to consider.
Or, maybe Congress will legislate a nonliability provision, or even a command.
