Due to price fluctuations, the effective weightings of the fund units may deviate from the specified target weightings of the investment strategy. If the weighting of a fund deviates from the target weighting by more than one percentage point, your entire portfolio will be realigned. Investments are sold and purchased to restore the target weightings of the individual index funds. This process is called rebalancing. It is performed monthly on the first banking day of the month, always before trading. There are no transaction costs involved.
