you can keep the money in cash with many banks and receive almost nothing, but also pay nothing.
or you can invest in funds
if you invest in funds in comparison with a BVG fund you don’t have the downside protection, but you might make more. my employer for example only credited the minimum required on BVG (now 1%…)
I’m not sure how much your employer was crediting you, but if it’s only for 1 year and it is not a lot of money you can go for cash. If you really wanted and if you have cash outside of the pension, you could even use futures to get efficient exposure to equity markets for this year, with the added benefit of being more or less hedged on CHF.
I don’t have a comparison of fees, in general they seem to be around 0.30% + the fees in the funds. yes, a rip off.
other important considerations are: how long you expect to keep the money parked / do you plan to emigrate / which funds are available and how much they cost
I don’t have recomendations, but check out http://www.freizügigkeitskontovergleich.ch.
all banks have a product, in addition check out Swisscanto, http://www.independent-stiftung.ch, http://pens-expert.ch, http://www.liberty-vorsorge.ch/. But for 1 year only, I’d personally go for the simplest solution.
