Depreciation Ceiling or Limit

I have a requirement for a depreciation limit of 175,000 MXN, all my assets have a life time of 3 years (STL).

For example, I have an asset with cost 200,000 MXN with date placed in service 01-MAY-2013, prorate convention is following month, the accumulated depreciation at the end of IT life time should not pass of 175,000 MXN.

Every month the depreciation should be: 4861.11 MXN  starting on Jun 2013

I am expecting to see the 175,000 between the 3 years:

• year 1: 58333.33
• year 2: 58333.33
• year 3: 58333.33

If I use the depreciation limit option, the 175,000 MXN is not deferred between the 3 years of time life.

If I use the expense ceiling, the asset is fully depreciated for 200,000 MXN.
