Current Calculation for FY2019
*It subtracts impairment_reserve double from adjusted_cost
adjusted_cost
    = cost - eofy_reserve - salvage - impairment_reserve - impairment_reserve
    = 241749 - (219917 + 259*2 + 256) - 24175 - 1000 - 1000
    = -5117

Theoretical YTD
    = trunc((adjusted_cost + Salvage value) * Rate)
    = trunc((-5117 + 24175) * 0.142)
    = 2706

Period Depreciation
    = round(Theoretical YTD * (1/12))
    = round(2706 * (1/12))
    = 226                     <--Wrong

Expected Calculation for FY2019
adjusted_cost
    = cost - eofy_reserve - salvage - impairment_reserve
    = 241749 - (219917 + 259*2 + 256) - 24175 - 1000
    = -4117

Theoretical YTD
    = trunc((adjusted_cost + Salvage value) * Rate)
    = trunc((-4117 + 24175) * 0.142)
    = 2848

Period Depreciation
    = round(Theoretical YTD * (1/12))
    = round(2848 * (1/12))
