Decrements: Decrement3
Exit Description
A description of the type of decrement to be investigated.
A different description for each of the types of decrement will enable identification when browsing the output and displaying the results.
Modes of Exit
Select one or more Modes of Exit to be investigated from the list.
Any number of modes of exit can be specified to be investigated in combination to represent one cause of exit (for example when you are investigating all forms of age retirement – normal, early and late).
Start Age
The Start Age is the minimum age at which investigation results will be output to the file (or in the review of the investigation, the graphical display).
Note that the results for all ages are calculated (and saved). The Start Age can be adjusted when reviewing the investigation results.
End Age
The End Age is the maximum age at which investigation results will be output to the file (or in the review of the investigation, the graphical display).
It is rounded to the next highest multiple of the Grouping of Data factor from the Start Age.
Note that the results for all ages are calculated (and saved). The End Age can be adjusted when reviewing the investigation results.
Grouping of Results
The Grouping of Data factor determines the size of the age sub-divisions used to summarise investigation results output to the file (or in the review of the investigation, the graphical display).
Note that the results for all ages are calculated (and saved). The Grouping of Data factor can be adjusted when reviewing the investigation results.
Upper Limit of Durations Analysed
Specify the Upper Limits of the Durations to be investigated (subject to the limit that only 20 years of durational experience is stored).
To enable you to build durational specific rates of withdrawal, the exposure and actual exits for all decrement investigation runs are calculated by both age and duration (up to 20 years, beyond that is grouped into an “ultimate” group).
You can specify a series of upper limits of Durations to be Analysed in
which decrements will be investigated. The lower limit will be one
greater than the previous upper limit specified. If, say, the first
upper limit specified is 5, rates will be calculated in respect of
exits and exposure contributed in the first five years of Scheme
membership.
If ultimate rates only are required, specify an upper limit greater than
20, eg the default of 99 suggested.
A separate page of output will be produced for the durations between each pair of durations specified.
Note that the exposure and number of exits is saved for all durations up to 20 years so the upper limits on the Durational Ranges can be subsequently changed when producing the graphical displays.
Save the Results for Sub Groups
The results (for all files or sub-groups combined) of every investigation are always saved (to a saved results file). These results are stored using the description applied to the parameter set when saved.
This option allows you to also save the results for each of the files or sub-groups specified as well. These results are stored using the description of the saved parameter set with a suffix of the sub-group data filename.
Stored results for each of the sub-groups means that:
- males and females can be investigated simultaneously but separate results can be reviewed; and/or
- the appropriateness of the Rate Table found to be the best fit for the whole group can be checked against each of the sub-groups.
It is possible to delete stored investigation results when reviewing the investigation. It is recommended that any results for inappropriate groupings such as heterogeneous groups (eg males and females combined when the decrement should clearly be different) or any small groups (for which comparisons are not reliable) or for any runs containing erroneous data should be deleted to avoid possible error.
Expected Table
The Rate Table Code of the expected table for comparison with the
actual Scheme experience.
The starting point for the comparison table is generally the expected
table that was assumed at the previous investigation.

Selecting rate tables
Rate tables can be selected by any of the following methods:
- Right-click on the field for a list of appropriate Rate Tables. For a field that will accept more than one type of Rate Table (e.g. Miscellaneous Tables), the list will be restricted to the current Table Type specified in the field – if you wish to see all allowable Rate Tables, delete the Table Type from the field before clicking; or
- Double Clicking on the field will produce the Rate Tables form where Rate Tables can be viewed (numerically and graphically) and Rate Tables can be added or edited. A Rate Table can be selected by pressing the Select button or double clicking on the Rate Table description in the tree; or
- the list of allowable Rate Tables can be scrolled through by
pressing the
<or>keys. The description of the Rate Table to the right of the field will change as each new Table is selected.
Age Rating
Any Rate Table can be rated up or down by a number of years as required
to make the rate at every age lighter or heavier than in the
original table.
A value of +10 will result, for example, in the value selected for a
30 year old actually being the rate for a 40 year old and for a value of
-5 would mean that the value at age 25 is selected.
If an age rating of a fraction of a year is required, a new table will have to be created through the Edit rate table option on the Rate Table form.
Percentage Adjustment
A percentage adjustment can be made to either a Rate Table or a Salary.
The Rate Tables can be adjusted by a percentage loading to make the decrement rate lighter or heavier than the original table. The salary for new entrants can be loaded to reflect changes in the salary profile.
Enter the number as percentage above 100% i.e. if a loading of 110% is
required then enter 10 or if a loading of 90% then enter -10. If no
adjustment is required then leave blank.
Durational Weight Table
In connection with the ability to calculate Durational Specific rates of
withdrawal, if the Expected Exits Table Type is a Withdrawal (or
Leaving Service) Table, a Withdrawal Durational Weight Table may be
applied to the standard table.
