Oh well, I guess I asked for that

Yes, that's what I meant, I think things were clear in my brain and didn't come out like that.
Funny, because I've just received a mail from my HR and now I have to fill in these forms, and tell them about a "vested benefits account" to put the compulsory part of the money. And I'm going to receive the overflow from this compulsory part.
I'm already arranging a meeting with the lady to understand better, but can you help me in advance?
This vested benefits account will basically be similar to a private pension fund account, right? Earning interest that I will then receive once I reach retirement age (or 5 years earlier).
Are there big differences between these accounts in different banks, in terms of interest? I have an account with UBS and maybe it'd be easier to stay with them.
I'll probably have to transfer out the extra money I'll receive, no point in keeping it here at 0.5% interest (their 'savings' account

)
