Need Czech Republic Depreciation Rate Tables

I am running Oracle Assets 11.5.10.2 without localizations.  I need to manually create the deprecation rate tables for the Czech Republic that cover the following asset groups:

  3 year assets 1st year 20%  -  remaining years 40%

  5 year assets 1st year 11%  -  remaining years 22.25%

10 year assets 1st year 5.5%  -  remaining years 10.5%

20 year assets 1st year 2.15%  -  remaining years 5.15%

30 year assets 1st year 1.4%  -  remaining years 3.4%

50 year assets 1st year 1.02%  -  remaining years 2.02%

Depreciation will be run monthly.  There are 12 periods in the year and a Yearly prorate convention.

Does anyone have depreciation rate tables that follow these specifics.

Thanks,

SC
