Variable Interest and Interest Rate Adjustment
Use
Two types of entries are required to represent the variable interest rate.
Prerequisites
We recommend that you maintain the reference interest rate table regularly to ensure that current data is available for interest rate fixing.
Procedure
By inserting a simple plus sign to link the variable interest and the reference interest rate in condition type Variable interest, you can enter these directly in the initial entry screen or in the Condition Details screen.
To define more complicated calculation formulas, choose the Formula button at the top of the Condition Details screen. Select a formula in the next screen by double-clicking one. In the following screen, enter the variables.
The remaining entry fields in this condition item are the same as those for entering nominal interest for fixed-interest percentage-quoted bonds.
The screen is divided into two areas: Interest rate adjustment and Interest fixing:
The Single dates function displays the interest rate adjustments which recur annually and which you cannot display via At start of period and Frequency with fixed date.

Interest rate adjustment takes place annually on 03/15 and 10/15.
You can only show this irregular sequence of interest rate adjustment dates via Single dates.
In the field below, enter how many days beforehand the interest rate fixing is to take place.
Also define which calendar you want to use for determining the date.
