Useful lives to compute Depreciation [S. 123, Sch II]

PART ‘A’

  1. Depreciation is the systematic allocation of the depreciable amount of an asset over its useful life.

Depreciation = Depreciable amount of an asset÷divided by useful life of such asset

The depreciable amount of an asset = the cost of an asset or other amount substituted for cost, less its residual value.

The useful life of an asset → the period over which an asset is expected to be available for use by an entity, or the number of production or similar units expected to be obtained from the asset by the entity.

  1. For the purpose of this Schedule, the term depreciation includes amortisation.
  2. Without prejudice to the foregoing provisions of paragraph 1,—
    1. The useful life of an asset shall not ordinarily be different from the useful life specified in Part C and the residual value of an asset shall not be > 5% of the original cost of the asset:
      Provided that where a company adopts a useful life different from what is specified in Part C or uses a residual value different from the limit specified above, the financial statements shall disclose such difference and provide justification in this behalf duly supported by technical advice;
    2. For intangible assests, the relevant Indian Accounting Standards (Ind AS) shall apply. Where a company is not required to comply with the Indian Accounting Standards (Ind AS), it shall comply with relevant Accounting Standards under Companies (Accounting Standards) Rules, 2006.", except in case of intangible assets (Toll Roads) created under ‘Build, Operate and Transfer’, ‘Build, Own, Operate and Transfer’ or any other form of public private partnership route in case of road projects.

PART ‘B’

  1. The useful life or residual value of any specific asset, as notified for accounting purposes by a Regulatory Authority constituted under an Act of Parliament or by the Central Government shall be applied in calculating the depreciation to be provided for such asset irrespective of the requirements of this Schedule.

Notes.

  1. "Factory buildings" does not include offices, godowns, staff quarters.
  2. Where, during any financial year, any additionhas been made to any asset, or where any asset has been sold, discarded, demolished or destroyed, the depreciation on such assets shall be calculated on a pro ratabasis from the date of such addition or, as the case may be, up to the date on which such asset has been sold, discarded, demolished or destroyed.
  3. The following information shall also be disclosed in the accounts, namely:—
  1. depreciation methods used; and
  2. the useful lives of the assets for computing depreciation, if they are different from the life specified in the Schedule.
  1. Useful life specified in part C of the schedule is for whole of the asset and where cost of a part of the asset is significant to total cost of the asset and useful life of that part is different from the useful life of the remaining asset, useful life of that significant part shall be determined separately. - voluntary in respect of FY commencing on or after the 1st April, 2014 and mandatory for FS in respect of FYs commencing on or after the 1st April, 2015.
  2. The useful lives of assets working on shiftbasis have been specified in the Schedule based on their single shift working. Except for assets in respect of which no extra shift depreciation is permitted (indicated by NESD in Part C above), if an asset is used for any time during the year for double shift, the depreciation will increase by 50% for that period and in case of the triple shift the depreciation shall be calculated on the basis of 100% for that period.
  3. From the date this Schedule comes into effect, the carrying amount of the assetas on that date—
    1. shall be depreciated over the remaining useful life of the asset as per this Schedule;
    2. after retaining the residual value, may be recognized in the opening balance of retained earnings where the remaining useful life of an asset is nil.
  4. ‘‘Continuous process plant’’ means a plant which is required and designed to operate for 24 hours a day.
