We have also gone through the provisions of Section 43(1) as well as Explanation 10 thereof. We noted that Section 43(1) defines the actual cost to mean the actual cost of the assets of the assessee reduced by that portion of the cost thereof, if any, as has been met directly or indirectly by other person or authority. In the impugned case, we noted that what the ICICI has financed by way of conditional grant to the assessee is the amount received from USA under the project grant agreement for the Program for Acceleration of Commercial Energy Research. Now the question arises whether USA can be regarded to be a person or authority. In our view, this provision cannot be read without Explanation 10. From the reading of the said explanation, it is explicitly clear that if a portion of a cost of an asset acquired by the assessee has been met directly or indirectly by Central Government or State Government or any authority established under any law or by any other person in the form of a subsidy or a grant or reimbursement, said subsidy grant or reimbursement as is relatable to the asset shall be reduced out of the actual cost of the assessee to the assessee. USA is a sovereign and cannot be Central Government or State Government or any authority established by any law in India
