As far as I am aware, you will HAVE TO take the money from Pilar II out of the company fund and pay 6% tax on it if you move outside CH and to a non-EU country. After tax the money will be put in a bank account specified by you. Once you have the cash, you can either invest it abroad ot leave it in a life insurance etc in CH there are old posts from Richard that detail the options. You can call insurance companies and see what they offer.
Compare the option leaving the money in CH (love return but high security ? is that still valid today?) to the retun on investment of your new home country.
There is a currency risk component inbedded in the decision as well. Do you know the country where you will retire? Then maybe you invest in that curreny? This is the FX roulette of modern times.
Boris is right : pilar I will be payed out once you reach reitrement age (CH legal) and can't me moved out of CH.
