A hire-purchase or other transaction under which the use and enjoyment of an asset is obtained by a person for a period at the end of which the property in the asset will or may pass to that person shall be treated for the purposes of this Act, both in relation to that person and in relation to the person from whom he obtains the use and enjoyment of the asset, as if it amounted to an entire disposal of the asset to that person at the beginning of the period for which he obtains the use and enjoyment of the asset, but subject to such adjustments of tax, whether by way of repayment or discharge of tax or otherwise, as may be required where the period for which that person has the use and enjoyment of the asset terminates without the property in the asset passing to him.
