I don't understand how Depriciation and adjustment amount is calculated.

 I built an used asset with original value 2400(CNY),   720(CNY) YTD depriciation, 2 life year,0 salvage,Date in service is 2013-05-01,Prorate Convention is NEXT_MONTH,Amortization NBV over Remaining Life is not allowed and save the asset.

 

    Then I adjusted  the asset cost to 4800(CNY) and selected  the Amortize Adjustment, Amortize start date is 2013-11-01,Current period is FEB-14.

 

   Run depreciation and found current total depreciation is 1135.28,include 196.32 Depriciation amount and 938.96  Adjustment Amount.

 

   I don't understand how this amount is calculated.
