Hard Issue: How to setup this uncommon Depreciation Method??

Question

Hello All, thanks very much for reading my thread.
We faced an hard issue on FA.
Scenarios:
according to client's company policy, assets should can be depreciated after useful life! For example:
Asset "A", life year is 4 years. During 4 years, each year depreciation is "Cost * (1 / (Life + 1))" , after 4 years, each year depreciation is "Previous year depreciation * 1/2" until asset "A" is retired.
Year Depreciation
1 cost * 1/5
2 cost * 1/5
3 cost * 1/5
4 cost * 1/5
5 cost * 1/5 * 1/2
6 cost * 1/10 * 1/2
7 cost * 1/20 * 1/2
Do R12 can meet above requirement ? We try to use "Formula Depreciation Method" to setup, but finally we found Oracle Ebs NOT allow depreciate after useful year. In addition, does ebs R12 can set asset continuing depreciation after useful year????
If you are setting the Depreciation Method Formula, what is the formula you will give??
Do you have any proposal ?
Thanks a lot!! ^_^

Hello,
For uncommon depreciation methods, i usually do an "Unplanned Depreciation" on the asset. That is, I calculate it manually and adjust the depreciation.
Well this might be a workaround if ever no one come up with a standard solution.
