The facts are agreed. The taxpayer, which is a life assurance company within the meaning of Div. 8 of Pt III of the Act, was incorporated in Victoria and during the relevant year of income carried on business (inter alia) in Australia, New Zealand and the United Kingdom. The taxpayer's principal offices in New Zealand and the United Kingdom respectively were in the buildings on the lands at Featherstone Street, Wellington and Basinghall Avenue, London, in respect of which the deductions are claimed. The uses to which these premises were put will later be discussed in a little more detail. The building at Featherstone Street, Wellington, had been erected by the taxpayer upon lands of which it had become the lessee under three separate leases, for different terms, but nothing turns on this fact or on the provisions of the leases. It is not disputed that the taxpayer incurred expenditure in making improvements not subject to tenant rights on the land at Featherstone Street, Wellington, or that the improvements were made with the written consent of the lessor or that the amount claimed represents a proportionate part of the amount of that expenditure arrived at by calculations made as required by s. 88 (2) of the Act. The land at Basinghall Avenue, London, and the building erected thereon had been leased to the taxpayer by the Corporation of the City of London. By a building agreement, dated 9th February 1959, the Corporation agreed to grant to an English company, Wool Exchange and General Investments Ltd., a lease of the land at Basinghall Avenue, London, and of the new building which Wool Exchange and General Investments Ltd. thereby agreed to erect thereon, for a term commencing from the date of completion of the new building to the satisfaction of the City Engineer and expiring on 25th December 2070. By a further agreement, dated 14th October 1959, between the taxpayer and Wool Exchange and General Investments Ltd. (therein called "the vendor"), it was agreed that in consideration of the sum of £stg.950,000 to be paid by the taxpayer to the vendor in the manner therein mentioned the vendor would either procure the Corporation to grant to the taxpayer such lease as by the building agreement was agreed to be granted to the vendor, or would, if the Corporation so required, procure such lease to be granted to the vendor in the first instance and would immediately afterwards assign it to the taxpayer. The sum of £stg.950,000 was paid by the taxpayer to Wool Exchange and General Investments Ltd. and on 20th July 1960, after the completion of the building to the satisfaction of the City Engineer, the Corporation granted a lease of the land to the taxpayer as from 8th June 1960 for a term expiring on 25th December 2070. If the sum of £stg.950,000 was a premium within s. 88 (1) it is not disputed that the amount claimed represents a proportionate part of that premium calculated in accordance with the subsection.
