(1) Subject to subsection (2), the rate of interest that is to be specified under paragraph 17(3)(d) in a certificate of entitlement in relation to a further advance that a person may seek from a credit provider is the rate of interest per year (disregarding section 35AA) of the last preceding previous advance.
(2) If, at the time when subsidy is or was most recently payable in relation to the last preceding previous advance, subsidy is or was payable in respect of the person in relation to one or more other previous advances:
(a) the rates of interest that are to be specified under paragraph 17(3)(c) in a certificate of entitlement in relation to a further advance that a person may seek from the credit provider are the rates of interest per year that applied (disregarding section 35AA) to those previous advances; and
(b) in relation to each such interest rate--the proportion of the further advance to be so specified in relation to that interest rate is the proportion of the sum of amounts outstanding in respect of all the previous advances that are amounts to which that interest rate applies.
(2A) For the purposes of this section, in determining the rate of interest that was payable in relation to a previous advance at any time before 5 January 1998, apply sections 35AB and 35AC as if the application of those sections were not limited to the calculation of interest for 5 January 1998 and later days.
(3) In this section:
"previous advance" , in relation to a further advance in respect of a person, means an advance (whether a Corporation advance, initial advance, additional advance or further advance) in respect of which the person is or was a borrower, or a contract of sale, in respect of which the person is or was a purchaser, preceding the further advance in question.
