ABAW - Post Impairment Asset

Hi Experts,

I have the below query

Scenario - Asset bought for $100000 on 01/01/2014, depreciation executed on 9/30/2014 $3750

                 Company wants to impair full $100000 on 10/31/2014. There should not be any NBV value left

ABAW was executed on 10/31/2014

AFAB was executed on 10/31/2014, we see $100000 was reversed, however accumulated depreciation was reversed upto 3365.38 instead of $3750

Transaction key ( Z81 - Impairment Loss current year) used

Asset value date - 01/01/2014

Any thoughts , why the accumulated depreciation is not getting fully reversed.

Thanks

SB
