Additional depreciation

In F.Y:-14-15, I have opening Capital Work in progress Balance of some amount. During the year I have allocated it to the respective assets on commencement of commercial production. All the assets have been acquired in this previous year only. My commercial production began on 01.01.2015. Now my query is whether i will get the benefit of additional depreciationj on the total amount (i.e., allocated+ actual cost) or only at actual cost( as CWIP pertains to earlier years)?

Kindly suggest.
