Does anyone know which percentage of their bitcoins Bitstamp is keeping in cold storage?

In case of an inputs.io-like SNAFU, which % of your coins do you think you'll see back?

Also... When an exchange like that get owned (as obviously happens once in a while) and see their bitcoins stolen, will they use your account balance in EUR / USD to reimburse everybody?

(btw I opened an account there and scanned my driving license and an utility bill and I'm now verified)
