Procedure documentationEditing the Calculation Group Box

 

In the Calculation group box on the Time Periods tab page, you edit the fields for a condition that belong to date category 220010 Calculation.

In this group box, you define the calculation period and the frequency with which the condition is calculated.

You specify the first calculation day that is the period end of the first calculation period. The start of the first calculation period is determined by the valid-from date of the condition. If the valid-from date of the condition does not correspond to the time period, then the first period is either reduced or extended. All other periods are calculated according to the time periods set up. The system adds the repetition unit to the first calculation day to determine the period end date of the following periods. The last calculation period can, for example, be brought forward as a result of the transaction term end.

The calculation can be periodic, or it can be based on the settings of another date category, or you can create individual calculation dates during the calendar year. This means you have the following options for the date update:

  • Periodic date update

  • Relative date update

  • Date update with annual set of dates

Procedure

You can make the following settings:

  • You can enter a working day shift for the future periodic dates.

    The working day shift specifies whether, and by how many days, the determined date is to be shifted if it falls on a Sunday or a public holiday.

    For more information, see Shifting Dates

  • You can enter up to five calendars for the working day shift.

    If you enter the working day shift, enter at least one calendar for this.

    Note Note

    The system uses the calendars that you enter to calculate a working day based on the working day shift. A working day must be a working day in all the calendars.

    End of the note.

  • In the Bring Due Date Forward field, you can specify the way in which the due date is to be processed if the calculation period is reduced, for example, before the term start or after the fixing end.

Periodic date update

To calculate the condition amount periodically, choose the value Periodic in the Frequency Category field.

You can make the following settings:

  1. Enter the frequency in the Repetition Period und Repetition Unit fields.

  2. Enter the first calculation day (start date) that is the period end of the first calculation period.

  3. You can flag the start date as inclusive, meaning that the calculation day is inclusive in all periods.

  4. You can enter a number of calendar days to postpone the date or bring it forward (negative plus/minus sign).

  5. Alternatively, you can enter a reference date for the start date. This means that the calculation is adapted, for example, to the contract start or the fixing start date.

  6. You can enter a one-time shift for the reference date.

  7. You can enter one or more key days on which the periodic calculation is to take place. If you enter 31, each month is set to the last day of the month.

    Example Example

    The start date is on 01/28/2008 if the update is periodic, and the frequency is monthly.

    If you enter 28 for the key day, the system always updates the date on the 28th of the month. 02/28/2008, 03/28/2008, 04/27/2008, 05/28/2008 and so on would then follow.

    If you enter 31 for the key day, the system always updates the date on the last day of the month. 02/29/2008, 03/30/2008, 04/30/2008, 05/31/2008 and so on would then follow.

    End of the example.

  8. If you enter the working day shift, you can select the Fixed Periods checkbox. The system then updates the data with fixed periods. This means that if a date is moved due to a working day shift, the moved date is the starting point for continued update.

Relative date update

To calculate the condition amount in relation to a reference date, enter Relative in the Frequency Category field.

You can make the following settings:

  1. You can specify whether the date taken from the reference date is inclusive.

  2. You can enter a number of calendar days to postpone the date or bring it forward (negative plus/minus sign).

  3. You can calculate the calculation date in relation to the due date or the periodic settlement. Enter one of the following reference date categories:

  4. You can use the Reference Date After Working Day Shift checkbox to specify that the calculation date refers to the reference date after its working day shift.

Date update with annual set of dates

To calculate the condition amount on particular dates during the calendar year, enter Annual Block of Dates in the Frequency Category field.

You can make the following settings:

  1. Enter the first calculation day (start date) that is the period end of the first calculation period.

  2. You can flag the start date as inclusive, meaning that the end of the calculation period is inclusive. This means that the period start is exclusive.

  3. You can enter a key day on which the periodic calculation is to take place. If you enter 31, each month is set to the last day of the month.

    Example Example

    You entered start date 01/01/2007 and 02/28 in the annual block of dates.

    If you enter 28 for the key day, the system annually updates the date on 02/28. 02/28/2007, 02/28/2008 and so on would follow.

    If you enter 31 for the key day, the system annually updates the date on the last day of the month. 02/28/2007, 02/29/2008, 02/28/2009 and so on would follow.

    End of the example.

  4. Enter at least one date in the Annual Block of Dates.

Result

You have defined the date update for the calculation.
