What is the Impact of adding a 'Fixed return' value to an asset?

The fixed return percentage in an Asset is completely separate from the stochastic forecasting.

We use the fixed return that is entered to grow the asset by. The fixed return is not reduced by tax, so if 5% is entered, for example, this is what the asset grows by. However, charges that you have entered on the asset will reduce the fixed rate return.

You cannot edit fixed rate assets in a Revised plan, as they usually has a set tranche and after that point, you cannot add to the investment, change the fixed rate or withdraw money without incurring a penalty.

We do not want the fixed rate to be accidentally changed, or further investment added to it, but a withdrawal can still be entered.
