Concept of block of assets is not applicable for PU
Depreciation is allowed on actual cost in respect of each plant and asset separately, without concept of block of asset. Though one can club all assets falling under same description and rate of depreciation, however, due to special provision for terminal depreciation actual cost, depreciation actually allowed and WDV of each asset need to be computed.
In case of sale etc. of any asset, a terminal depreciation, if any, will be allowed separately and simple treatment in case of block of assets on which depreciation on WDV basis is allowed, is not applicable in case of PU.

Concept of Block of asset can be extended to depreciable assets of PU and provision of terminal depreciation can be omitted.
Definition for block of assets of PU, cost of such block of assets of PU, and written down value of block of such assets of PU can be inserted.
This will introduce simplicity and easy recording in case of PU, as in case of other assesses in whose case depreciation is allowed on written down value on basis of block of assets.
Option to PU to adopt Cost basis and WDV basis can be introduced to provide flexibility to PU.
