(iii)  Extra depreciation allowance for approved hotels:

        An extra allowance of depreciation of an amount equal to one-half of the normal allowance shall be allowed in the case of machinery and plant installed by an assessee, being an Indian company, in premises used by it as a hotel where such hotel is for the time being approved by the Central Government for the purposes of section 33 of the Act.

        Explanation: For the purposes of this sub-item and sub-item (iv), normal allowance means the amount of depreciation allowance [other than the extra depreciation allowance under this sub-item or the extra shift depreciation allowance under sub-item (iv)] which is allowable under rule 5.

²¹(iv)    Extra shift depreciation allowance:

        An extra allowance up to a maximum of an amount equal to one-half of the normal allowance shall be allowed where a concern claims such allowance on account of double shift working and establishes that it has worked double shift. An extra allowance up to a maximum of an amount equal to the normal allowance, instead of one-half of the normal allowance, shall be allowed where a concern claims such allowance on account of triple shift working and establishes that it has worked triple shift.

        The calculations of the extra allowance for double shift working and for triple shift working shall be made separately in the proportion which the number of days for which the concern worked double shift or triple shift, as the case may be, bears to the normal number of working days during the previous year.

        For this purpose, the normal number of working days during the previous year shall be deemed to be

  (a)  in the case of a seasonal factory or concern, the number of days on which the factory or concern actually worked during the previous year or 180 days, whichever is greater;

  (b)  in any other case, the number of days on which the factory or concern actually worked during the previous year or 240 days, whichever is greater.

Illustration

        For example, where a non-seasonal concern worked 270 days during the previous year out of which it worked triple shift on 135 days and double shift on another 90 days, the extra depreciation allowance for triple shift working will be 135/270, i.e., one-half, of the normal allowance, and that for double shift working 90/270, i.e., one-third, of one-half, of the normal allowance.

        The extra shift allowance shall not be allowed in respect of any item of machinery or plant which has been specifically excepted by inscription of the letters N.E.S.A. (meaning No Extra Shift Allowance) against it in sub-item (ii) above and also in respect of the following items of machinery and plant to which the general rate of depreciation of ²²[15] per cent applies
