The underlying pools will contribute pro-rata (on value) to the overall cost of insurance, safekeeping and administration fees.  Pools will not subsidise each other.  Fees are generally around 1% p.a. for the Gold pool and 0.8% p.a. for the Silver and Platinum pools. The asset manager will charge a performance fee based on the performance in the trading pool, generally up to 1/5 of nett profits made. The unit price of a pool will reflect the fees deducted from that pool.
