It will be observed that s. 20 (5) refers to three classes of expenditure: the first, that exclusively incurred in gaining what I may shortly call premium income, the second, that exclusively incurred in gaining or producing the income included in the assessment, and the third, that part incurred in the general management of the business of the company but not including any expenditure incurred in gaining or producing the income included in the assessment. It recognizes that the expenditure of a company is not always exclusively incurred for the production of premium or assessable or non-assessable income, but may be undertaken for the general business purposes of the company, as, for instance, the class of expenditure often referred to as overhead expenses. But the classification of expenditure in s. 20 (5) is, I think, exhaustive: that which is not exclusively incurred in gaining premium income or assessable income is incurred in the general management of the business of the company.
His Honour thus equates the "expenditure incurred in the general management of the business of the company" with expenditure "undertaken for the general business purposes of the company" of which overhead expenses provide an instance. In that case, his Honour was not concerned to distinguish between expenditure of a mixed character which did, and expenditure of that character which did not, fall within the description "general management"; the issue was whether the expenditure in question was exclusively incurred in gaining non-assessable income and his Honour held that it was so incurred. It follows that the present problem was not that to which his Honour was directing his consideration and his judgment is not authority for the precise scope of the phrase "general management" nor do I, as already stated, accept the view that that phrase is synonymous with the carrying on of a company's business. Nevertheless, it is apparent that his Honour perceived no very narrow limitations which were to be placed upon the phrase; to that extent the judgment in that case is at least in no way opposed to the view which I have formed.
