depreciation after revaluation

Hello,

I have read that in a situation where an asset is revalued, IAS 16 allows for a transfer of an amount equal to excess depreciation to be made from the revaluation reserve to retained earnings. So I would like to confirm……..is it that the entity has a choice between 1.doing that and 2.charging the depreciation to the profit & loss?

Also, if they do indeed have a choice then what determines the treatment chosen by the entity?

Thanks
