Yes very good - thanks for this. I saw this before - but just to reiterate for others who may not have seen it - RE retirement accounts:
"Because assets in these accounts are subject to a separate set of tax rules in both the United States and the United Kingdom, none of the rules regarding either PFICs or “non-reporting” funds apply if the funds in question are held inside a qualified retirement account. Therefore, a U.S. citizen building up a retirement nest egg through a UK employer provided pension plan needn’t be concerned that the investments in the plan are PFICs"
