We look at your holdings at the end of each month and suggest a balance (your Suggested Minimum Cash Balance) that should be sufficient to meet any fees or any other outgoings that may arise for the next few months. Please note that it would be impossible to predict your fees accurately in all circumstances. The value of funds will rise and fall (and therefore so will your fees) and any significant increase in the value of your holding during a month may mean you have to adjust the balance of cash you hold. However, it should prove a good guide in most cases.
