Then in Year 4, Quarter 1 you revalue the asset again using a revaluation rate of -10%

Acc. Depre.Exp =  Existing Acc. Depre.Exp + [Existing Acc.Depr.Exp * (Revaluation Rate/100)]
Acc. Depre.Exp =  2000 + [2000 * (5/100)]

Revaluation Reserve = Existing Revaluation Reserve + (Change in Note Book Value)
Revaluation Reserve = 0 + (8400-8000)
Change in Note Book Value = [Reval1 => 10,500 - 2100] - [Asset Cost - Acc. Depre. Expense]
New Depre. Exp. = New Asset Cost[10,500]/20
