(1)The cost to the lender of allowing the use of money or land shall be taken to be equal to the consideration which might be expected in a transaction on the same terms as those on which the use is allowed (apart from terms as to consideration) made at arm's length between persons not connected with each other.
(2)The cost to the lender of allowing the use of property other than money or land shall be taken to be equal to the aggregate of—
(a)the annual value of the use of the property or, if the use does not continue throughout the year, a proportionate part of that annual value, and
(b)any expense incurred by the lender in connection with property during the year or, if the use does not continue throughout the year, a proportionate part of that expense, but excluding expense incurred in the acquisition or production of the property and excluding any hire charges;
except that if the property is hired by the lender and the annual amount of the hire charges is greater than the annual value of the use of the property, paragraph (a) above shall have effect as if it referred to that annual amount instead of to that annual value.
(3)If the property is money or land, the amount arrived at under section 115(1) above shall be reduced by the income tax which would be chargeable in respect of that amount (after taking account in the case of land of any deductions which might be made for the purposes of Schedule A) if it were the highest part of the lender's total income ; and in calculating that income there shall be disregarded any such sum as is mentioned in paragraphs (a) to (c) of section 529 of the Taxes Act.
