Depreciation as per companies act 2013 for wdv

Dear All,

I am using the WDV method for calculating the depreciation. Now to comply with Companies Act 2013, I am calculating the depreciation using the useful life of the asset as prescribed in the Schedule II instead of calculating the rates.

My Query : Will I have to calculate the amount with retrospective effect? Will it be considered as change in the method of calculating depreciation?

Thanks in advance

Regards,
