Good day sir, if the revaluation of PPE falls in the middle of the financial year do we calculate depreciation by including the other part of the year? For example we revalue a building on the 1st of June 20X8 which we had already been depreciated for 6 years and it has a useful life of 20 years. Do we then depreciate by diving by 13.5years or we just use 13 years.
