This sounds likely a way of parking a lorry in a car park.
It’s the wrong vehicle in the wrong place at the wrong time. Pension schemes may not be convenient for American parents but they are very important to the pensioners and those who will be pensioners in years to come.
So long as we get American sponsors thinking that fiduciary management teams (dressed as trustees ) can park the UK pension lorry in a car park, we will continue to advertise our pension schemes as a nuisance.
Instead, we should be returning the pensions to the people who drive the cars – the ordinary people. 
We need the people making decisions about the parking of the big trucks that are our occupational pensions, getting the pensions to deliver the goods.
Pensions need to be managed for the people who are beneficiaries, not as a management problem to be minimised by business people.
