Each member of the ship co-ownerships mentioned in article 8 quater depreciates the cost price of its share of ownership in accordance with the procedures laid down in respect of ships; for the purposes of determining capital gains, the depreciation applied is deducted from the cost price.
The provisions of the first paragraph apply to financial years beginning on or after 1 January 1978. The depreciation deducted for tax purposes by the co-ownership in respect of previous financial years is divided between the co-owners in proportion to their rights in order to determine, for each share of ownership, the residual value remaining to be depreciated.
